Add initial support for Renesas Ethernet-TSN End-station device of R-Car
V4H. The Ethernet End-station can connect to an Ethernet network using a
10 Mbps, 100 Mbps, or 1 Gbps full-duplex link via MII/GMII/RMII/RGMII.
Depending on the connected PHY.
The driver supports Rx checksum and offload and hardware timestamps.
While full power management and suspend/resume is not yet supported the
driver enables runtime PM in order to enable the module clock. While
explicit clock management using clk_enable() would suffice for the
supported SoC, the module could be reused on SoCs where the module is
part of a power domain.

Most of the logic in qca8k_port_bridge_join() and qca8k_port_bridge_leave()
is the same. Refactor to reduce duplication and prepare for reusing the
code for implementing bridge port isolation.
dsa_port_offloads_bridge_dev() is used instead of
dsa_port_offloads_bridge(), passing the bridge in as a struct netdevice *,
as we won't have a struct dsa_bridge in qca8k_port_bridge_flags().
The error handling is changed slightly in the bridge leave case,
returning early and emitting an error message when a regmap access fails.
This shouldn't matter in practice, as there isn't much we can do if
communication with the switch breaks down in the middle of reconfiguration.

qca8k_port_bridge_join() set QCA8K_PORT_LOOKUP_CTRL() for i == port twice,
once in the loop handling all other port's masks, and finally at the end
with the accumulated port_mask.
The first time it would incorrectly set the port's own bit in the mask,
only to correct the mistake a moment later. qca8k_port_bridge_leave() had
the same issue, but here the regmap_clear_bits() was a no-op rather than
setting an unintended value.
Remove the duplicate assignment by skipping the whole loop iteration for
i == port. The unintended bit setting doesn't seem to have any negative
effects (even when not reverted right away), so the change is submitted
as a simple cleanup rather than a fix.

====================
l2tp: don't use the tunnel socket's sk_user_data in datapath
This series refactors l2tp to not use the tunnel socket's sk_user_data
in the datapath. The main reasons for doing this are
* to allow for simplifying internal socket cleanup code (to be done
in a later series)
* to support multiple L2TPv3 UDP tunnels using the same 5-tuple
address
When handling received UDP frames, l2tp's current approach is to look
up a session in a per-tunnel list. l2tp uses the tunnel socket's
sk_user_data to derive the tunnel context from the receiving socket.
But this results in the socket and tunnel lifetimes being very tightly
coupled and the tunnel/socket cleanup paths being complicated. The
latter has historically been a source of l2tp bugs and makes the code
more difficult to maintain. Also, if sockets are aliased, we can't
trust that the socket's sk_user_data references the right tunnel
anyway. Hence the desire to not use sk_user_data in the datapath.
The new approach is to lookup sessions in a per-net session list
without first deriving the tunnel:
* For L2TPv2, the l2tp header has separate tunnel ID and session ID
fields which can be trivially combined to make a unique 32-bit key
for per-net session lookup.
* For L2TPv3, there is no tunnel ID in the packet header, only a
session ID, which should be unique over all tunnels so can be used
as a key for per-net session lookup. However, this only works when
the L2TPv3 session ID really is unique over all tunnels. At least
one L2TPv3 application is known to use the same session ID in
different L2TPv3 UDP tunnels, relying on UDP address/ports to
distinguish them. This worked previously because sessions in UDP
tunnels were kept in a per-tunnel list. To retain support for this,
L2TPv3 session ID collisions are managed using a separate per-net
session hlist, keyed by ID and sk. When looking up a session by ID,
if there's more than one match, sk is used to find the right one.
L2TPv3 sessions in IP-encap tunnels are already looked up by session
ID in a per-net list. This work has UDP sessions also use the per-net
session list, while allowing for session ID collisions. The existing
per-tunnel hlist becomes a plain list since it is used only in
management and cleanup paths to walk a list of sessions in a given
tunnel.
For better performance, the per-net session lists use IDR. Separate
IDRs are used for L2TPv2 and L2TPv3 sessions to avoid potential key
collisions.
These changes pass l2tp regression tests and improve data forwarding
performance by about 10% in some of my test setups.

The per-tunnel session list is no longer used by the
datapath. However, we still need a list of sessions in the tunnel for
l2tp_session_get_nth, which is used by management code. (An
alternative might be to walk each session IDR list, matching only
sessions of a given tunnel.)
Replace the per-tunnel hlist with a per-tunnel list. In functions
which walk a list of sessions of a tunnel, walk this list instead.

Modify UDP decap to not use the tunnel pointer which comes from the
sock's sk_user_data when parsing the L2TP header. By looking up the
destination session using only the packet contents we avoid potential
UDP 5-tuple aliasing issues which arise from depending on the socket
that received the packet.
Drop the useless error messages on short packet or on failing to find
a session since the tunnel pointer might point to a different tunnel
if multiple sockets use the same 5-tuple.
Short packets (those not big enough to contain an L2TP header) are no
longer counted in the tunnel's invalid counter because we can't derive
the tunnel until we parse the l2tp header to lookup the session.
l2tp_udp_encap_recv was a small wrapper around l2tp_udp_recv_core which
used sk_user_data to derive a tunnel pointer in an RCU-safe way. But
we no longer need the tunnel pointer, so remove that code and combine
the two functions.

L2TPv2 sessions are currently kept in a per-tunnel hashlist, keyed by
16-bit session_id. When handling received L2TPv2 packets, we need to
first derive the tunnel using the 16-bit tunnel_id or sock, then
lookup the session in a per-tunnel hlist using the 16-bit session_id.
We want to avoid using sk_user_data in the datapath and double lookups
on every packet. So instead, use a per-net IDR to hold L2TPv2
sessions, keyed by a 32-bit value derived from the 16-bit tunnel_id
and session_id. This will allow the L2TPv2 UDP receive datapath to
lookup a session with a single lookup without deriving the tunnel
first.
L2TPv2 sessions are held in their own IDR to avoid potential
key collisions with L2TPv3 sessions.

L2TPv3 sessions are currently held in one of two fixed-size hash
lists: either a per-net hashlist (IP-encap), or a per-tunnel hashlist
(UDP-encap), keyed by the L2TPv3 32-bit session_id.
In order to lookup L2TPv3 sessions in UDP-encap tunnels efficiently
without finding the tunnel first via sk_user_data, UDP sessions are
now kept in a per-net session list, keyed by session ID. Convert the
existing per-net hashlist to use an IDR for better performance when
there are many sessions and have L2TPv3 UDP sessions use the same IDR.
Although the L2TPv3 RFC states that the session ID alone identifies
the session, our implementation has allowed the same session ID to be
used in different L2TP UDP tunnels. To retain support for this, a new
per-net session hashtable is used, keyed by the sock and session
ID. If on creating a new session, a session already exists with that
ID in the IDR, the colliding sessions are added to the new hashtable
and the existing IDR entry is flagged. When looking up sessions, the
approach is to first check the IDR and if no unflagged match is found,
check the new hashtable. The sock is made available to session getters
where session ID collisions are to be considered. In this way, the new
hashtable is used only for session ID collisions so can be kept small.
For managing session removal, we need a list of colliding sessions
matching a given ID in order to update or remove the IDR entry of the
ID. This is necessary to detect session ID collisions when future
sessions are created. The list head is allocated on first collision
of a given ID and refcounted.

New drivers were prevented from adding ndo_set_vf_* callbacks
over the last few years. This was expected to result in broader
switchdev adoption, but seems to have had little effect.
Based on recent netdev meeting there is broad support for allowing
adding those ops.
There is a problem with the current API supporting a limited number
of VFs (100+, which is less than some modern HW supports).
We can try to solve it by adding similar functionality on devlink
ports, but that'd be another API variation to maintain.
So a netlink attribute reshuffling is a more likely outcome.
Document the guidance, make it clear that the API is frozen.

The KSZ9477 allows HSR in-HW offloading for any of two selected ports.
This patch adds check if one tries to use more than two ports with
HSR offloading enabled.
The problem is with RedBox configuration (HSR-SAN) - when configuring:
ip link add name hsr0 type hsr slave1 lan1 slave2 lan2 interlink lan3 \
supervision 45 version 1
The lan1 (port0) and lan2 (port1) are correctly configured as ports, which
can use HSR offloading on ksz9477.
However, when we do already have two bits set in hsr_ports, we need to
return (-ENOTSUPP), so the interlink port (lan3) would be used with
SW based HSR RedBox support.
Otherwise, I do see some strange network behavior, as some HSR frames are
visible on non-HSR network and vice versa.
This causes the switch connected to interlink port (lan3) to drop frames
and no communication is possible.
Moreover, conceptually - the interlink (i.e. HSR-SAN port - lan3/port2)
shall be only supported in software as it is also possible to use ksz9477
with only SW based HSR (i.e. port0/1 -> hsr0 with offloading, port2 ->
HSR-SAN/interlink, port4/5 -> hsr1 with SW based HSR).

bnxt_en: implement netdev_queue_mgmt_ops
Implement netdev_queue_mgmt_ops for bnxt added in [1]. This will be used
in the io_uring ZC Rx patchset to configure queues with a custom page
pool w/ a special memory provider for zero copy support.
The first two patches prep the driver, while the final patch adds the
implementation.
Any arbitrary Rx queue can be reset without affecting other queues. V2
and prior of this patchset was thought to only support resetting queues
not in the main RSS context. Upon further testing I realised moving
queues out and calling bnxt_hwrm_vnic_update() wasn't necessary.
I didn't include the netdev core API using this netdev_queue_mgmt_ops
because Mina is adding it in his devmem TCP series [2]. But I'm happy to
include it if folks want to include a user with this series.
I tested this series on BCM957504-N1100FY4 with FW 229.1.123.0. I
manually injected failures at all the places that can return an errno
and confirmed that the device/queue is never left in a broken state.

Implement netdev_queue_mgmt_ops for bnxt added in [1].
Two bnxt_rx_ring_info structs are allocated to hold the new/old queue
memory. Queue memory is copied from/to the main bp->rx_ring[idx]
bnxt_rx_ring_info.
Queue memory is pre-allocated in bnxt_queue_mem_alloc() into a clone,
and then copied into bp->rx_ring[idx] in bnxt_queue_mem_start().
Similarly, when bp->rx_ring[idx] is stopped its queue memory is copied
into a clone, and then freed later in bnxt_queue_mem_free().
I tested this patchset with netdev_rx_queue_restart(), including
inducing errors in all places that returns an error code. In all cases,
the queue is left in a good working state.
Rx queues are created/destroyed using bnxt_hwrm_rx_ring_alloc() and
bnxt_hwrm_rx_ring_free(), which issue HWRM_RING_ALLOC and HWRM_RING_FREE
commands respectively to the firmware. By the time a HWRM_RING_FREE
response is received, there won't be any more completions from that
queue.

Convert ptp-qoirq from txt to yaml format.
Additional change:
- Fixed example interrupts proptery. Need only 1 irq by check MPC8313 spec.
- Move Reference clock context under clk,sel.
- Interrupts is not required property.
- Use low case for hex value.
- Check reference manual of MPC8313, p1010 and so on, which dts use more
than 1 irqs. Only 1 irq for each ptp device. Check driver code
(drivers/ptp/ptp_qoriq.c) and only 1 irq used. So original description is
wrong.
- Remove comments for compatible string.

Embedding net_device into structures prohibits the usage of flexible
arrays in the net_device structure. For more details, see the discussion
at [1].
Un-embed the net_devices from struct mt76_dev by converting them
into pointers, and allocating them dynamically. Use the leverage
alloc_netdev_dummy() to allocate the net_device object at
mt76_dma_init().
The free of the device occurs at mt76_dma_cleanup().

These drivers don't use the driver_data member of struct i2c_device_id,
so don't explicitly initialize this member.
This prepares putting driver_data in an anonymous union which requires
either no initialization or named designators. But it's also a nice
cleanup on its own.

The current code only restores PTP tx_avail count when we get DMA
mapping errors. Fix it so that the PTP tx_avail count will be
restored for both DMA mapping errors and skb_pad() errors.
Otherwise PTP TX timestamp will not be available after a PTP
packet hits the skb_pad() error.

Firmware will now advertise a non-zero TSO max segments if the
device has a limit. 0 means no limit. The latest 5760X chip
(early revs) has a limit of 2047 that cannot be exceeded. If
exceeded, the chip will send out just a small number of segments.
Call netif_set_tso_max_segs() if the device has a limit.
