This completes the previous patches by moving notifier registration for
SF dev tables outside the devlink locked critical section in
mlx5_init_one() / mlx5_uninit_one() and into the mlx5_mdev_init() /
mlx5_mdev_uninit() functions.
This is only done for non-SFs, since SFs do not have a SF HW table
themselves.
After this patch, notifiers can grab the PF devlink lock (soon to be
necessary) without creating a locking cycle.

The vhca event notifier consists of an atomic notifier for vhca state
changes (used for SF events), multiple workqueues and a blocking
notifier chain for delivering the vhca state change events for further
processing.
This patch moves the vhca notifier head outside of mlx5_init_one() /
mlx5_uninit_one() and into the mlx5_mdev_init() / mlx5_mdev_uninit()
functions.
This allows called notifiers to grab the PF devlink lock which was
previously impossible because it would create a circular lock
dependency.
mlx5_vhca_event_stop() is now called earlier in the cleanup phase and
flushes the workqueues to ensure that after the call, there are no
pending events. This simplifies the cleanup flow for vhca event
consumers.

Move event init/cleanup outside of mlx5_init_one() / mlx5_uninit_one()

By doing this, we avoid the events being reinitialized on devlink reload
and, more importantly, the events->sw_nh notifier chain becomes
available earlier in the init procedure, which will be used in
subsequent patches. This makes sense because the events struct is pure
software, independent of any HW details.

In case of a FW issue, FW might be not responding to FW commands,
causing kernel lockout for a long period of time, e.g. rtnl_lock held
while ethtool is trying to collect stats waiting for FW to respond to
multiple commands, when all of them will timeout.
While there's no immediate indication of the FW lockout, we can safely
assume that something is wrong when all command slots are busy and in
a timeout state and no FW completion was received on any of them.
In such case, start immediately failing new commands.

Extend the TX timestamp handler to recover the SQ when the difference
between the port and CQE TX timestamps is abnormally large.
The current logic aborts timestamp delivery if the delta exceeds
1/128 seconds, which matches the maximum expected packet interval in
ptp4l. A larger delta makes the timestamps unreliable.
This change adds recovery if the delta exceeds 0.5 seconds. Such a
large gap should not occur in normal operation and indicates that
firmware is stuck or metadata tracking is out of sync, leading to stale
or mismatched timestamps. Recovering the SQ ensures forward progress
and avoids silently dropping invalid timestamps.
The timestamp handler now takes mlx5e_ptpsq directly to access both CQ
stats and the recovery state.

By overlaying the struct gve_xdp_buff on top of the struct xdp_buff_xsk
that AF_XDP utilizes, the driver records the 32 bit timestamp via the
completion descriptor and the cached 64 bit NIC timestamp via gve_priv.
The driver's implementation of xmo_rx_timestamp extends the timestamp to
the full and up to date 64 bit timestamp and returns it to the user.
gve_rx_xsk_dqo is modified to accept a pointer to the completion
descriptor and no longer takes a buf_len explicitly as it can be pulled
out of the descriptor.
With this patch gve now supports bpf_xdp_metadata_rx_timestamp.

Previously, gve had been only initializing ptp aux work when
hardware timestamping was initialized through ndo_hwtsatmp_set. As this
patch series introduces XDP hardware timestamp metadata which will
require the ptp aux work, the work can't be gated on the
kernel_hwtstamp_config being set and must be initialized elsewhere.
For simplicity, ptp_schedule_worker is invoked right after the ptp_clock
is registered with the kernel (which happens during gve_probe or
following reset). The worker is scheduled in GVE_NIC_TS_SYNC_INTERVAL_MS
as the synchronous call to gve_clock_nic_ts_read makes the worker
redundant if scheduled immediately.
If gve cannot read the device clock immediately, it errors out of
gve_init_clock.

On the Renesas RZ/V2H EVK platform, where the stmmac MAC is connected to a
Microchip KSZ9131RNXI PHY, creating or deleting VLAN interfaces may fail
with timeouts:
# ip link add link end1 name end1.5 type vlan id 5
15c40000.ethernet end1: Timeout accessing MAC_VLAN_Tag_Filter
RTNETLINK answers: Device or resource busy
Disabling EEE at runtime avoids the problem:
# ethtool --set-eee end1 eee off
# ip link add link end1 name end1.5 type vlan id 5
# ip link del end1.5
The stmmac hardware requires the receive clock to be running when writing
certain registers, such as those used for MAC address configuration or
VLAN filtering. However, by default the driver enables Energy Efficient
Ethernet (EEE) and allows the PHY to stop the receive clock when the link
is idle. As a result, the RX clock might be stopped when attempting to
access these registers, leading to timeouts and other issues.
Commit dd557266cf ("net: stmmac: block PHY RXC clock-stop")
addressed this issue for most register accesses by wrapping them in
phylink_rx_clk_stop_block()/phylink_rx_clk_stop_unblock() calls.
However, VLAN add/delete operations may be invoked with bottom halves
disabled, where sleeping is not allowed, so using these helpers is not
possible.
Therefore, to fix this, disable the RX clock stop feature in the phylink
configuration if VLAN features are set. This ensures the RX clock remains
active and register accesses succeed during VLAN operations.

When the "rx-vlan-filter" feature is enabled on a network device, the 8021q
module automatically adds a VLAN 0 hardware filter when the device is
brought administratively up.
For stmmac, this causes vlan_add_hw_rx_fltr() to create a new entry for
VID 0 in the mac_device_info->vlan_filter array, in the following format:
VLAN_TAG_DATA_ETV | VLAN_TAG_DATA_VEN | vid
Here, VLAN_TAG_DATA_VEN indicates that the hardware filter is enabled for
that VID.
However, on the delete path, vlan_del_hw_rx_fltr() searches the vlan_filter
array by VID only, without verifying whether a VLAN entry is enabled. As a
result, when the 8021q module attempts to remove VLAN 0, the function may
mistakenly match a zero-initialized slot rather than the actual VLAN 0
entry, causing incorrect deletions and leaving stale entries in the
hardware table.
Fix this by verifying that the VLAN entry's enable bit (VLAN_TAG_DATA_VEN)
is set before matching and deleting by VID. This ensures only active VLAN
entries are removed and avoids leaving stale entries in the VLAN filter
table, particularly for VLAN ID 0.

Due to not having access to chip documentation there isn't much I can

fbnic supports pause frames. When pause frames are enabled presumably
user expects lossless operation from the NIC. Make sure we configure
RDE (Rx DMA Engine) to DROP_NEVER mode to avoid discards due to delays
in fetching Rx descriptors from the host.
While at it enable DROP_NEVER when NIC only has a single queue
configured. In this case the NIC acts as a FIFO so there's no risk
of head-of-line blocking other queues by making RDE wait. If pause
is disabled this just moves the packet loss from the DMA engine to
the Rx buffer.
Remove redundant call to fbnic_config_drop_mode_rcq(), introduced by

fbnic_enable_rcq(), which is called immediately afterward, already
