2019-02-07ath10k: add a condition to fill the LDPC capability correctlySurabhi Vishnoi
The firmware advertises the LDPC support information for HT in HT capability info in the wmi service ready event. To provide granularity, firmware now advertises WMI_HT_CAP_RX_LDPC and WMI_HT_CAP_TX_LDPC separately. To support LDPC, host should also check for WMI_HT_CAP_RX_LDPC and WMI_HT_CAP_TX_LDPC in HT capabilities. Add a condition to existing logic in host to know whether firmware supports LDPC or not.

2019-02-07ath10k: reduce transmit msdu countAlagu Sankar
Reduce the transmit MSDU count for SDIO, to match with the descriptors as used by the firmware. This also acts as a high watermark level for transmit. Too many packets to the firmware results in transmit overflow interrupt. It only affect SDIO chip, it will not cause functionaly changes to other hardware.

When calling debugfs functions, they can now return error values if something went wrong. If that happens, return a NULL as a *dentry to the relay core instead of passing it an illegal pointer. The relay core should be able to handle an illegal pointer, but add this check to be safe.

2019-02-07ath10k: fix hw-restart crash inject mode for WCN3990Rakesh Pillai
The hw-restart crash inject mode is a special mode, where there is no crash generated in the firmware, but instead the driver restarts the firmware. In order to restart WCN3990 firmware, the driver needs to send qmi_wlan_disable message followed by the qmi_wlan_enable message to the WCN3990 firmware. Currently the qmi_wlan_disable message is not sent to the WCN3990 firmware when hw-restart crash is injected, which causes the firmware to crash when the driver sends qmi_wlan_enable message during ath10k_restart. Send qmi_wlan_disable to the WCN3990 firmware when the hw-restart crash is injected via debugfs.

2019-02-06net: stmmac: fix ptp timestamping on Rx on gmac4Ilias Apalodimas
The current driver only enables Pdelay_Req and Pdelay_Resp when HWTSTAMP_FILTER_PTP_V2_EVENT, HWTSTAMP_FILTER_PTP_V1_L4_EVENT or HWTSTAMP_FILTER_PTP_V2_L4_EVENT is requested. This results in ptp sync on slave mode to report 'received SYNC without timestamp' when using ptp4l. Although the hardware can support Sync, Pdelay_Req and Pdelay_resp by setting bit14 annd bits 17/16 to 01 this leaves Delay_Req timestamps out. Fix this by enabling all event and general messages timestamps. This includes SYNC, Follow_Up, Delay_Req, Delay_Resp, Pdelay_Req, Pdelay_Resp and Pdelay_Resp_Follow_Up messages.

On one hand, the mv88e6xxx driver has a work queue called in loop which will attempt register accesses after MDIO bus suspension, that entirely freezes the platform during suspend. On the other hand, the DSA core is not ready yet to support suspend to RAM operation because so far there is no way to recover reliably the switch configuration. To avoid the kernel to freeze when suspending with a switch driven by the mv88e6xxx driver, we choose to prevent the driver suspension and in the same way, the whole platform.

This feature has been used in shipping products from 2.6.32 based kernels. Its tied with RDS v4.1 protocol version and the compatibility gets negotiated as part of connections setup. Patchset keeps full backward compatibility using existing connection negotiation scheme. Currently the feature is exploited by RDMA transport and for TCP transport the user tos values are mapped to same default class (0). For RDMA transports, RDMA CM service type API is used to set up different SL(service lanes) and the IB fabric is configured for tos mapping using Subnet Manager(SL to VL mappings). Similarly for ROCE fabric, user priority is mapped with different DSCP code points which are associated with different switch queues in the fabric. The original code was developed by Bang Nguyen in downstream kernel back in 2.6.32 kernel days and it has evolved significantly over period of time.

Ido Schimmel says: ==================== mlxsw: Offload blackhole routes Blackhole routes are routes that cause matching packets to be silently dropped. This is in contrast to unreachable routes that generate an ICMP host unreachable packet in response. The driver currently programs both route types with a trap action and lets the kernel drop matching packets. This is sub-optimal as packets routed using a blackhole route can be directly dropped by the ASIC. Patch #1 alters mlxsw to program blackhole routes with a discard action.

2019-02-06net: Introduce ndo_get_port_parent_id()Florian Fainelli
In preparation for getting rid of switchdev_ops, create a dedicated NDO operation for getting the port's parent identifier. There are essentially two classes of drivers that need to implement getting the port's parent ID which are VF/PF drivers with a built-in switch, and pure switchdev drivers such as mlxsw, ocelot, dsa etc. We introduce a helper function: dev_get_port_parent_id() which supports recursion into the lower devices to obtain the first port's parent ID. Convert the bridge, core and ipv4 multicast routing code to check for such ndo_get_port_parent_id() and call the helper function when valid before falling back to switchdev_port_attr_get(). This will allow us to convert all relevant drivers in one go instead of having to implement both switchdev_port_attr_get() and ndo_get_port_parent_id() operations, then get rid of switchdev_port_attr_get().

While in NAPI context, free skbs by calling napi_consume_skb() instead of dev_kfree_skb(), to take advantage of the bulk freeing mechanism. Signed-off-by: Ioana Radulescu <ruxandra.radulescu@nxp.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-02-06dpaa2-eth: Use a single page per Rx bufferIoana Ciocoi Radulescu
Instead of allocating page fragments via the network stack, use the page allocator directly. For now, we consume one page for each Rx buffer. With the new memory model we are free to consider adding more XDP support. Performance decreases slightly in some IP forwarding cases. No visible effect on termination traffic. The driver memory footprint increases as a result of this change, but it is still small enough to not really matter. Another side effect is that now Rx buffer alignment requirements are naturally satisfied without any additional actions needed. Remove alignment related code, except in the buffer layout information conveyed to MC, as hardware still needs to know the alignment value we guarantee.

2019-02-06Merge branch 'add-flow_rule-infrastructure'David S. Miller
Pablo Neira Ayuso says: ==================== add flow_rule infrastructure This patchset, as is, allows us to reuse the driver codebase to configure ACL hardware offloads for the ethtool_rxnfc and the TC flower interfaces. A few clients for this infrastructure are presented, such as the bcm_sf2 and the qede drivers, for reference. Moreover all of the existing drivers in the tree are converted to use this infrastructure. This patchset is re-using the existing flow dissector infrastructure that was introduced by Jiri Pirko et al. so the amount of abstractions that this patchset adds are minimal. Well, just a few wrapper structures for the selector side of the rules. And, in order to express actions, this patchset exposes an action API that is based on the existing TC action infrastructure and what existing drivers already support on that front. v7: This patchset is a rebase on top of the net-next tree, after addressing questions and feedback from driver developers in the last batch. ==================== Signed-off-by: David S.

2019-02-06qede: use ethtool_rx_flow_rule() to remove duplicated parser codePablo Neira Ayuso
The qede driver supports for ethtool_rx_flow_spec and flower, both codebases look very similar. This patch uses the ethtool_rx_flow_rule() infrastructure to remove the duplicated ethtool_rx_flow_spec parser and consolidate ACL offload support around the flow_rule infrastructure. Furthermore, more code can be consolidated by merging qede_add_cls_rule() and qede_add_tc_flower_fltr(), these two functions also look very similar. This driver currently provides simple ACL support, such as 5-tuple matching, drop policy and queue to CPU. Drivers that support more features can benefit from this infrastructure to save even more redundant codebase. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org> Signed-off-by: David S.

2019-02-06qede: place ethtool_rx_flow_spec after code after TC flower codebasePablo Neira Ayuso
This is a preparation patch to reuse the existing TC flower codebase from ethtool_rx_flow_spec. This patch is merely moving the core ethtool_rx_flow_spec parser after tc flower offload driver code so we can skip a few forward function declarations in the follow up patch.

2019-02-06dsa: bcm_sf2: use flow_rule infrastructurePablo Neira Ayuso
Update this driver to use the flow_rule infrastructure, hence we can use the same code to populate hardware IR from ethtool_rx_flow and the cls_flower interfaces.
