- help
- This allows you to use COPS AppleTalk cards to connect to LocalTalk
- networks. You also need version 1.3.3 or later of the netatalk
- package. This driver is experimental, which means that it may not
- work. This driver will only work if you choose "AppleTalk DDP"
- networking support, above.
- Please read the file
- <file:Documentation/networking/device_drivers/appletalk/cops.rst>.

-config IPDDP
- tristate "Appletalk-IP driver support"
- depends on DEV_APPLETALK && ATALK
- help
- This allows IP networking for users who only have AppleTalk
- networking available. This feature is experimental. With this
- driver, you can encapsulate IP inside AppleTalk (e.g. if your Linux
- box is stuck on an AppleTalk only network) or decapsulate (e.g. if
- you want your Linux box to act as an Internet gateway for a zoo of
- AppleTalk connected Macs). Please see the file
- <file:Documentation/networking/ipddp.rst> for more information.
-
- If you say Y here, the AppleTalk-IP support will be compiled into
- the kernel. In this case, you can either use encapsulation or
- decapsulation, but not both. With the following two questions, you
- decide which one you want.
-
- To compile the AppleTalk-IP support as a module, choose M here: the
- module will be called ipddp.
- In this case, you will be able to use both encapsulation and
- decapsulation simultaneously, by loading two copies of the module
- and specifying different values for the module option ipddp_mode.
-
-config IPDDP_ENCAP
- bool "IP to Appletalk-IP Encapsulation support"
- depends on IPDDP
- help
- If you say Y here, the AppleTalk-IP code will be able to encapsulate
- IP packets inside AppleTalk frames; this is useful if your Linux box
- is stuck on an AppleTalk network (which hopefully contains a
- decapsulator somewhere). Please see
- <file:Documentation/networking/ipddp.rst> for more information.

- * this driver.
- *
- * This driver has 2 modes and they are: Dayna mode and Tangent mode.
- * Each mode corresponds with the type of card. It has been found
- * that there are 2 main types of cards and all other cards are
- * the same and just have different names or only have minor differences
- * such as more IO ports. As this driver is tested it will
- * become more clear on exactly what cards are supported. The driver
- * defaults to using Dayna mode. To change the drivers mode, simply
- * select Dayna or Tangent mode when configuring the kernel.
- *
- * This driver should support:
- * TANGENT driver mode:
- * Tangent ATB-II, Novell NL-1000, Daystar Digital LT-200,
- * COPS LT-1
- * DAYNA driver mode:
- * Dayna DL2000/DaynaTalk PC (Half Length), COPS LT-95,
- * Farallon PhoneNET PC III, Farallon PhoneNET PC II
- * Other cards possibly supported mode unknown though:
- * Dayna DL2000 (Full length), COPS LT/M (Micro-Channel)
- *
- * Cards NOT supported by this driver but supported by the ltpc.c
- * driver written by Bradford W. Johnson <johns393@maroon.tc.umn.edu>
- * Farallon PhoneNET PC
- * Original Apple LocalTalk PC card
- *
- * N.B.
- *
- * The Daystar Digital LT200 boards do not support interrupt-driven
- * IO. You must specify 'irq=0xff' as a module parameter to invoke
- * polled mode. I also believe that the port probing logic is quite
- * dangerous at best and certainly hopeless for a polled card. Best to

- * Theory of Operation:
- *
- * About 3/4 of the mailboxes (get_mb_rx_first()...get_mb_rx_last())
- * on the chip are reserved for RX. We split them into 2 groups. The
- * lower group ranges from get_mb_rx_first() to get_mb_rx_low_last().
- *
- * Like it or not, but the chip always saves a received CAN message
- * into the first free mailbox it finds (starting with the
- * lowest). This makes it very difficult to read the messages in the
- * right order from the chip. This is how we work around that problem:
- *
- * The first message goes into mb nr. 1 and issues an interrupt. All
- * rx ints are disabled in the interrupt handler and a napi poll is
- * scheduled. We read the mailbox, but do _not_ re-enable the mb (to
- * receive another message).

- *
- * The variable priv->rx_next points to the next mailbox to read a
- * message from. As long we're in the lower mailboxes we just read the
- * mailbox but not re-enable it.
- *
- * With completion of the last of the lower mailboxes, we re-enable the
- * whole first group, but continue to look for filled mailboxes in the
- * upper mailboxes. Imagine the second group like overflow mailboxes,
- * which takes CAN messages if the lower goup is full. While in the

+ help
+ Support for C402 card family from esd electronics gmbh.
+ This card family is based on the ESDACC CAN controller and
+ available in several form factors: PCI, PCIe, PCIe Mini,
+ M.2 PCIe, CPCIserial, PMC, XMC (see https://esd.eu/en)
+
+ This driver can also be built as a module. In this case the
+ module will be called esd_402_pci.

+ *
+ * @ov: overview module structure
+ * @cores: array of core structures
+ *
+ * This function handles all interrupts pending for the overview module and the
+ * CAN cores of the esdACC FPGA.
+ *
+ * It examines for all cores (the overview module core and the CAN cores)
+ * the bmfifo.irq_cnt and compares it with the previously saved
+ * bmfifo.local_irq_cnt. An IRQ is pending if they differ. The esdACC FPGA
+ * updates the bmfifo.irq_cnt values by DMA.
+ *
+ * The pending interrupts are masked by writing to the IRQ mask register at
+ * ACC_OV_OF_BM_IRQ_MASK. This register has for each core a two bit command
+ * field evaluated as follows:
+ *
+ * Define, bit pattern: meaning
+ * 00: no action
+ * ACC_BM_IRQ_UNMASK, 01: unmask interrupt
+ * ACC_BM_IRQ_MASK, 10: mask interrupt
+ * 11: no action
+ *
+ * For each CAN core with a pending IRQ handle_core_interrupt() handles all
+ * busmaster messages from the message FIFO. The last handled message (FIFO
+ * index) is written to the CAN core to acknowledge its handling.
+ *
+ * Last step is to unmask all interrupts in the FPGA using
+ * ACC_BM_IRQ_UNMASK_ALL.
+ *
+ * Return:
+ * IRQ_HANDLED, if card generated an interrupt that was handled
+ * IRQ_NONE, if the interrupt is not ours

+ *
+ * The hardware has 64 possible table entries for bridges with one VLAN
+ * ID, one flow id and a list of ports for each bridge. All entries which
+ * match the same flow ID are combined in the mac learning table, they
+ * act as one global bridge.
+ * The hardware does not support VLAN filter on the port, but on the
+ * bridge, this driver converts the DSA model to the hardware.
+ *
+ * The CPU gets all the exception frames which do not match any forwarding
+ * rule and the CPU port is also added to all bridges. This makes it possible
+ * to handle all the special cases easily in software.
+ * At the initialization the driver allocates one bridge table entry for
+ * each switch port which is used when the port is used without an
+ * explicit bridge. This prevents the frames from being forwarded
+ * between all LAN ports by default.

- * The VLAN and bridge model the GSWIP hardware uses does not directly
- * matches the model DSA uses.
- *
- * The hardware has 64 possible table entries for bridges with one VLAN
- * ID, one flow id and a list of ports for each bridge. All entries which
- * match the same flow ID are combined in the mac learning table, they
- * act as one global bridge.
- * The hardware does not support VLAN filter on the port, but on the
- * bridge, this driver converts the DSA model to the hardware.
- *
- * The CPU gets all the exception frames which do not match any forwarding
- * rule and the CPU port is also added to all bridges. This makes it possible
- * to handle all the special cases easily in software.
- * At the initialization the driver allocates one bridge table entry for
- * each switch port which is used when the port is used without an
- * explicit bridge. This prevents the frames from being forwarded
- * between all LAN ports by default.

+ * @rx_pause: If true, enables receive pause.
+ *
+ * Description:
+ * The function configures flow control settings for a given port based on the
+ * desired settings and current duplex mode.
+ *
+ * According to the KSZ8873 datasheet, the PORT_FORCE_FLOW_CTRL bit in the
+ * Port Control 2 register (0x1A for Port 1, 0x22 for Port 2, 0x32 for Port 3)
+ * determines how flow control is handled on the port:
+ * "1 = will always enable full-duplex flow control on the port, regardless
+ * of AN result.
+ * 0 = full-duplex flow control is enabled based on AN result."
+ *
+ * This means that the flow control behavior depends on the state of this bit:
+ * - If PORT_FORCE_FLOW_CTRL is set to 1, the switch will ignore AN results and
+ * force flow control on the port.
+ * - If PORT_FORCE_FLOW_CTRL is set to 0, the switch will enable or disable
+ * flow control based on the AN results.
+ *
+ * However, there is a potential limitation in this configuration. It is
+ * currently not possible to force disable flow control on a port if we still
+ * advertise pause support. While such a configuration is not currently
+ * supported by Linux, and may not make practical sense, it's important to be
+ * aware of this limitation when working with the KSZ8873 and similar devices.

+ * together.
+ *
+ * If auto-negotiation is enabled, we usually allow the flow control to

+ * Hardware Management of EEE/LPI State:
+ * For KSZ switch ports with integrated PHYs (e.g., KSZ9893R ports 1-2),
+ * observation and testing suggest that the actual EEE / Low Power Idle (LPI)
+ * state transitions are managed autonomously by the hardware based on
+ * the auto-negotiation results. (Note: While the datasheet describes EEE
+ * operation based on negotiation, it doesn't explicitly detail the internal
+ * MAC/PHY interaction, so autonomous hardware management of the MAC state
+ * for LPI is inferred from observed behavior).
+ * This hardware control, consistent with the switch's ability to operate
+ * autonomously via strapping, means MAC-level software intervention is not
+ * required or exposed for managing the LPI state once EEE is negotiated.
+ * (Ref: KSZ9893R Data Sheet DS00002420D, primarily Section 4.7.5 explaining
+ * EEE, also Sections 4.1.7 on Auto-Negotiation and 3.2.1 on Configuration
+ * Straps).
+ *
+ * Additionally, ports configured as MAC interfaces (e.g., KSZ9893R port 3)
+ * lack documented MAC-level LPI control.
+ *
+ * Therefore, this callback performs no action and serves primarily to inform
+ * phylink of LPI awareness and to document the inferred hardware behavior.

+ *
+ * This function sets up the PHY address mapping for the LAN937x switches,

+ * 1. **SPI Access**: A straightforward one-to-one port-to-PHY address
+ * mapping is applied.
+ * 2. **MDIO Access**: The PHY address mapping varies based on chip variant
+ * and strap configuration. An offset is calculated based on strap settings
+ * to ensure correct PHY addresses are assigned. The offset calculation logic
+ * is based on Microchip's Article Number 000015828, available at:
+ * https://microchip.my.site.com/s/article/LAN9374-Virtual-PHY-PHY-Address-Mapping
+ *
+ * The function first checks if side MDIO access is disabled, in which case a
+ * simple direct mapping (port number = PHY address) is applied. If side MDIO
+ * access is enabled, it reads the strap configuration to determine the correct
+ * offset for PHY addresses.
+ *
+ * The appropriate mapping table is selected based on the chip ID, and the
+ * `phy_addr_map` is populated with the correct addresses for each port. Any
+ * port with no PHY is assigned a `LAN937X_NO_PHY` marker.

+ * lan937x_mdio_bus_preinit - Pre-initialize MDIO bus for accessing PHYs.
+ * @dev: Pointer to device structure.
+ * @side_mdio: Boolean indicating if the PHYs are accessed over a side MDIO bus.
+ *
+ * This function configures the LAN937x switch for PHY access either through
+ * SPI or the side MDIO bus, unlocking the necessary registers for each access
+ * mode.
+ *
+ * Operation Modes:
+ * 1. **SPI Access**: Enables SPI indirect access to address clock domain
+ * crossing issues when SPI is used for PHY access.
+ * 2. **MDIO Access**: Grants access to internal PHYs over the side MDIO bus,
+ * required when using the MDIO bus for PHY management.
+ *
+ * Return: 0 on success, error code on failure.

+/* In Clause 5 of IEEE Std 802-2014, two sublayers of the data link layer (DLL)
+ * of the Open Systems Interconnection basic reference model (OSI/RM) are
+ * described; the medium access control (MAC) and logical link control (LLC)
+ * sublayers. The MAC sublayer is the one facing the physical layer.
+ *
+ * In 8.2 of IEEE Std 802.1Q-2022, the Bridge architecture is described. A
+ * Bridge component comprises a MAC Relay Entity for interconnecting the Ports
+ * of the Bridge, at least two Ports, and higher layer entities with at least a
+ * Spanning Tree Protocol Entity included.
+ *
+ * Each Bridge Port also functions as an end station and shall provide the MAC
+ * Service to an LLC Entity. Each instance of the MAC Service is provided to a
+ * distinct LLC Entity that supports protocol identification, multiplexing, and
+ * demultiplexing, for protocol data unit (PDU) transmission and reception by
+ * one or more higher layer entities.
+ *
+ * It is described in 8.13.9 of IEEE Std 802.1Q-2022 that in a Bridge, the LLC
+ * Entity associated with each Bridge Port is modeled as being directly
+ * connected to the attached Local Area Network (LAN).
+ *
+ * On the switch with CPU port architecture, CPU port functions as Management
+ * Port, and the Management Port functionality is provided by software which
+ * functions as an end station. Software is connected to an IEEE 802 LAN that is
+ * wholly contained within the system that incorporates the Bridge. Software
+ * provides access to the LLC Entity associated with each Bridge Port by the
+ * value of the source port field on the special tag on the frame received by
+ * software.
+ *
+ * We call frames that carry control information to determine the active
+ * topology and current extent of each Virtual Local Area Network (VLAN), i.e.,
+ * spanning tree or Shortest Path Bridging (SPB) and Multiple VLAN Registration
+ * Protocol Data Units (MVRPDUs), and frames from other link constrained
+ * protocols, such as Extensible Authentication Protocol over LAN (EAPOL) and
+ * Link Layer Discovery Protocol (LLDP), link-local frames. They are not
+ * forwarded by a Bridge. Permanently configured entries in the filtering
+ * database (FDB) ensure that such frames are discarded by the Forwarding
+ * Process. In 8.6.3 of IEEE Std 802.1Q-2022, this is described in detail:
+ *
+ * Each of the reserved MAC addresses specified in Table 8-1
+ * (01-80-C2-00-00-[00,01,02,03,04,05,06,07,08,09,0A,0B,0C,0D,0E,0F]) shall be
+ * permanently configured in the FDB in C-VLAN components and ERs.
+ *
+ * Each of the reserved MAC addresses specified in Table 8-2
+ * (01-80-C2-00-00-[01,02,03,04,05,06,07,08,09,0A,0E]) shall be permanently
+ * configured in the FDB in S-VLAN components.
+ *
+ * Each of the reserved MAC addresses specified in Table 8-3
+ * (01-80-C2-00-00-[01,02,04,0E]) shall be permanently configured in the FDB in
+ * TPMR components.
+ *
+ * The FDB entries for reserved MAC addresses shall specify filtering for all
+ * Bridge Ports and all VIDs. Management shall not provide the capability to
+ * modify or remove entries for reserved MAC addresses.
+ *
+ * The addresses in Table 8-1, Table 8-2, and Table 8-3 determine the scope of
+ * propagation of PDUs within a Bridged Network, as follows:
+ *
+ * The Nearest Bridge group address (01-80-C2-00-00-0E) is an address that no
+ * conformant Two-Port MAC Relay (TPMR) component, Service VLAN (S-VLAN)
+ * component, Customer VLAN (C-VLAN) component, or MAC Bridge can forward.
+ * PDUs transmitted using this destination address, or any other addresses
+ * that appear in Table 8-1, Table 8-2, and Table 8-3
+ * (01-80-C2-00-00-[00,01,02,03,04,05,06,07,08,09,0A,0B,0C,0D,0E,0F]), can
+ * therefore travel no further than those stations that can be reached via a
+ * single individual LAN from the originating station.
+ *
+ * The Nearest non-TPMR Bridge group address (01-80-C2-00-00-03), is an
+ * address that no conformant S-VLAN component, C-VLAN component, or MAC
+ * Bridge can forward; however, this address is relayed by a TPMR component.
+ * PDUs using this destination address, or any of the other addresses that
+ * appear in both Table 8-1 and Table 8-2 but not in Table 8-3
+ * (01-80-C2-00-00-[00,03,05,06,07,08,09,0A,0B,0C,0D,0F]), will be relayed by
+ * any TPMRs but will propagate no further than the nearest S-VLAN component,
+ * C-VLAN component, or MAC Bridge.
+ *
+ * The Nearest Customer Bridge group address (01-80-C2-00-00-00) is an address
+ * that no conformant C-VLAN component, MAC Bridge can forward; however, it is
+ * relayed by TPMR components and S-VLAN components. PDUs using this
+ * destination address, or any of the other addresses that appear in Table 8-1
+ * but not in either Table 8-2 or Table 8-3 (01-80-C2-00-00-[00,0B,0C,0D,0F]),
+ * will be relayed by TPMR components and S-VLAN components but will propagate
+ * no further than the nearest C-VLAN component or MAC Bridge.
+ *
+ * Because the LLC Entity associated with each Bridge Port is provided via CPU
+ * port, we must not filter these frames but forward them to CPU port.
+ *
+ * In a Bridge, the transmission Port is majorly decided by ingress and egress
+ * rules, FDB, and spanning tree Port State functions of the Forwarding Process.
+ * For link-local frames, only CPU port should be designated as destination port
+ * in the FDB, and the other functions of the Forwarding Process must not
+ * interfere with the decision of the transmission Port. We call this process
+ * trapping frames to CPU port.
+ *
+ * Therefore, on the switch with CPU port architecture, link-local frames must
+ * be trapped to CPU port, and certain link-local frames received by a Port of a
+ * Bridge comprising a TPMR component or an S-VLAN component must be excluded
+ * from it.
+ *
+ * A Bridge of the switch with CPU port architecture cannot comprise a Two-Port
+ * MAC Relay (TPMR) component as a TPMR component supports only a subset of the
+ * functionality of a MAC Bridge. A Bridge comprising two Ports (Management Port
+ * doesn't count) of this architecture will either function as a standard MAC
+ * Bridge or a standard VLAN Bridge.
+ *
+ * Therefore, a Bridge of this architecture can only comprise S-VLAN components,
+ * C-VLAN components, or MAC Bridge components. Since there's no TPMR component,
+ * we don't need to relay PDUs using the destination addresses specified on the
+ * Nearest non-TPMR section, and the proportion of the Nearest Customer Bridge
+ * section where they must be relayed by TPMR components.
+ *
+ * One option to trap link-local frames to CPU port is to add static FDB entries
+ * with CPU port designated as destination port. However, because that
+ * Independent VLAN Learning (IVL) is being used on every VID, each entry only
+ * applies to a single VLAN Identifier (VID). For a Bridge comprising a MAC
+ * Bridge component or a C-VLAN component, there would have to be 16 times 4096
+ * entries. This switch intellectual property can only hold a maximum of 2048
+ * entries. Using this option, there also isn't a mechanism to prevent
+ * link-local frames from being discarded when the spanning tree Port State of
+ * the reception Port is discarding.
+ *
+ * The remaining option is to utilise the BPC, RGAC1, RGAC2, RGAC3, and RGAC4
+ * registers. Whilst this applies to every VID, it doesn't contain all of the
+ * reserved MAC addresses without affecting the remaining Standard Group MAC
+ * Addresses. The REV_UN frame tag utilised using the RGAC4 register covers the
+ * remaining 01-80-C2-00-00-[04,05,06,07,08,09,0A,0B,0C,0D,0F] destination
+ * addresses. It also includes the 01-80-C2-00-00-22 to 01-80-C2-00-00-FF
+ * destination addresses which may be relayed by MAC Bridges or VLAN Bridges.
+ * The latter option provides better but not complete conformance.
+ *
+ * This switch intellectual property also does not provide a mechanism to trap
+ * link-local frames with specific destination addresses to CPU port by Bridge,
+ * to conform to the filtering rules for the distinct Bridge components.
+ *
+ * Therefore, regardless of the type of the Bridge component, link-local frames
+ * with these destination addresses will be trapped to CPU port:
+ *
+ * 01-80-C2-00-00-[00,01,02,03,0E]
+ *
+ * In a Bridge comprising a MAC Bridge component or a C-VLAN component:
+ *
+ * Link-local frames with these destination addresses won't be trapped to CPU
+ * port which won't conform to IEEE Std 802.1Q-2022:
+ *
+ * 01-80-C2-00-00-[04,05,06,07,08,09,0A,0B,0C,0D,0F]
+ *
+ * In a Bridge comprising an S-VLAN component:
+ *
+ * Link-local frames with these destination addresses will be trapped to CPU
+ * port which won't conform to IEEE Std 802.1Q-2022:
+ *
+ * 01-80-C2-00-00-00
+ *
+ * Link-local frames with these destination addresses won't be trapped to CPU
+ * port which won't conform to IEEE Std 802.1Q-2022:
+ *
+ * 01-80-C2-00-00-[04,05,06,07,08,09,0A]
+ *
+ * To trap link-local frames to CPU port as conformant as this switch
+ * intellectual property can allow, link-local frames are made to be regarded as
+ * Bridge Protocol Data Units (BPDUs). This is because this switch intellectual
+ * property only lets the frames regarded as BPDUs bypass the spanning tree Port
+ * State function of the Forwarding Process.
+ *
+ * The only remaining interference is the ingress rules. When the reception Port
+ * has no PVID assigned on software, VLAN-untagged frames won't be allowed in.
+ * There doesn't seem to be a mechanism on the switch intellectual property to
+ * have link-local frames bypass this function of the Forwarding Process.

+ * - push_inner_tag=1: the inner tag is always pushed. This is good when the
+ * classified VLAN is not a discardable quantity (the port
+ * is under a VLAN-aware bridge, and software needs to
+ * continue processing the packet in the same VLAN as the

+ * The point is that what is good for a VLAN-unaware port is not good for a

+ *
+ * Hardware captures timestamps which contain only 32 bits of nominal
+ * nanoseconds, as opposed to the 64bit timestamps that the stack expects.
+ *
+ * Extend the 32bit nanosecond timestamp using the following algorithm and
+ * assumptions:
+ *
+ * 1) have a recently cached copy of the PHC time
+ * 2) assume that the in_tstamp was captured 2^31 nanoseconds (~2.1
+ * seconds) before or after the PHC time was captured.
+ * 3) calculate the delta between the cached time and the timestamp
+ * 4) if the delta is smaller than 2^31 nanoseconds, then the timestamp was
+ * captured after the PHC time. In this case, the full timestamp is just
+ * the cached PHC time plus the delta.
+ * 5) otherwise, if the delta is larger than 2^31 nanoseconds, then the
+ * timestamp was captured *before* the PHC time, i.e. because the PHC
+ * cache was updated after the timestamp was captured by hardware. In this
+ * case, the full timestamp is the cached time minus the inverse delta.
+ *
+ * This algorithm works even if the PHC time was updated after a Tx timestamp
+ * was requested, but before the Tx timestamp event was reported from
+ * hardware.
+ *
+ * This calculation primarily relies on keeping the cached PHC time up to
+ * date. If the timestamp was captured more than 2^31 nanoseconds after the
+ * PHC time, it is possible that the lower 32bits of PHC time have
+ * overflowed more than once, and we might generate an incorrect timestamp.
+ *
+ * This is prevented by (a) periodically updating the cached PHC time once
+ * a second, and (b) discarding any Tx timestamp packet if it has waited for
+ * a timestamp for more than one second.

-/**
- * ice_cfg_fw_log - configure FW logging
- * @hw: pointer to the HW struct
- * @enable: enable certain FW logging events if true, disable all if false
- *
- * This function enables/disables the FW logging via Rx CQ events and a UART
- * port based on predetermined configurations. FW logging via the Rx CQ can be
- * enabled/disabled for individual PF's. However, FW logging via the UART can
- * only be enabled/disabled for all PFs on the same device.
- *
- * To enable overall FW logging, the "cq_en" and "uart_en" enable bits in
- * hw->fw_log need to be set accordingly, e.g. based on user-provided input,
- * before initializing the device.
- *
- * When re/configuring FW logging, callers need to update the "cfg" elements of
- * the hw->fw_log.evnts array with the desired logging event configurations for
- * modules of interest. When disabling FW logging completely, the callers can
- * just pass false in the "enable" parameter. On completion, the function will
- * update the "cur" element of the hw->fw_log.evnts array with the resulting
- * logging event configurations of the modules that are being re/configured. FW
- * logging modules that are not part of a reconfiguration operation retain their
- * previous states.
- *
- * Before resetting the device, it is recommended that the driver disables FW
- * logging before shutting down the control queue. When disabling FW logging
- * ("enable" = false), the latest configurations of FW logging events stored in
- * hw->fw_log.evnts[] are not overridden to allow them to be reconfigured after
- * a device reset.
- *
- * When enabling FW logging to emit log messages via the Rx CQ during the
- * device's initialization phase, a mechanism alternative to interrupt handlers
- * needs to be used to extract FW log messages from the Rx CQ periodically and
- * to prevent the Rx CQ from being full and stalling other types of control
- * messages from FW to SW. Interrupts are typically disabled during the device's
- * initialization phase.

+ * Add that to our base aligned max_data (12K) and we have
