In the blamed commit, a rudimentary reallocation procedure for RX buffer
descriptors was implemented, for the situation when their format changes
between normal (no PTP) and extended (PTP).

enetc_hwtstamp_set() calls enetc_close() and enetc_open() in a sequence,
and this sequence loses information which was previously configured in
the TX BDR Mode Register, specifically via the enetc_set_bdr_prio() call.
The TX ring priority is configured by tc-mqprio and tc-taprio, and
affects important things for TSN such as the TX time of packets. The
issue manifests itself most visibly by the fact that isochron --txtime
reports premature packet transmissions when PTP is first enabled on an
enetc interface.

Save the TX ring priority in a new field in struct enetc_bdr (occupies a
2 byte hole on arm64) in order to make this survive a ring reconfiguration.

When fail to dma_map_single() in mtk_rx_alloc(), it returns directly.
But the memory allocated for local variable data is not freed, and
local variabel data has not been attached to ring->data[i] yet, so the

Commit 1229b339 ("ice: Add low latency Tx timestamp read") refactored
PTP timestamping logic to use a threaded IRQ instead of a separate kthread.

This implementation introduced ice_misc_intr_thread_fn and redefined the
ice_ptp_process_ts function interface to return a value of whether or not
the timestamp processing was complete.

ice_misc_intr_thread_fn would take the return value from ice_ptp_process_ts
and convert it into either IRQ_HANDLED if there were no more timestamps to
be processed, or IRQ_WAKE_THREAD if the thread should continue processing.

This is not correct, as the kernel does not re-schedule threaded IRQ
functions automatically. IRQ_WAKE_THREAD can only be used by the main IRQ
function.

This results in the ice_ptp_process_ts function (and in turn the
ice_ptp_tx_tstamp function) from only being called exactly once per
interrupt.

If an application sends a burst of Tx timestamps without waiting for a
response, the interrupt will trigger for the first timestamp. However,
later timestamps may not have arrived yet. This can result in dropped or
discarded timestamps. Worse, on E822 hardware this results in the interrupt
logic getting stuck such that no future interrupts will be triggered. The
result is complete loss of Tx timestamp functionality.

Fix this by modifying the ice_misc_intr_thread_fn to perform its own
polling of the ice_ptp_process_ts function. We sleep for a few microseconds
between attempts to avoid wasting significant CPU time. The value was
chosen to allow time for the Tx timestamps to complete without wasting so
much time that we overrun application wait budgets in the worst case.

The ice_ptp_process_ts function also currently returns false in the event
that the Tx tracker is not initialized. This would result in the threaded
IRQ handler never exiting if it gets started while the tracker is not
initialized.

Fix the function to appropriately return true when the tracker is not
initialized.

Note that this will not reproduce with default ptp4l behavior, as the
program always synchronously waits for a timestamp response before sending
another timestamp request.

The error is reflected in that it shows wrong splittable status of
port when executing "devlink port show".
The reason which leads the error is that the assigned operation of
splittable is just a simple negation operation of split and it does
not consider port lanes quantity. A splittable port should have
several lanes that can be split(lanes quantity > 1).
If without the judgement, it will show wrong message for some
firmware, such as 2x25G, 2x10G.

After commit aa626da9 ("iavf: Detach device during reset task")
the device is detached during reset task and re-attached at its end.
The problem occurs when reset task fails because Tx queues are
restarted during device re-attach and this leads later to a crash.

To resolve this issue properly close the net device in cause of
failure in reset task to avoid restarting of tx queues at the end.
Also replace the hacky manipulation with IFF_UP flag by device close
that clears properly both IFF_UP and __LINK_STATE_START flags.
In these case iavf_close() does not do anything because the adapter
state is already __IAVF_DOWN.

Reproducer:
1) Run some Tx traffic (e.g. iperf3) over iavf interface
2) Set VF trusted / untrusted in loop

[root@host ~]# cat repro.sh

PF=enp65s0f0

Recent commit aa626da9 ("iavf: Detach device during reset task")
removed netif_tx_stop_all_queues() with an assumption that Tx queues
are already stopped by netif_device_detach() in the beginning of
reset task. This assumption is incorrect because during reset
task a potential link event can start Tx queues again.
Revert this change to fix this issue.

Reproducer:
1. Run some Tx traffic (e.g. iperf3) over iavf interface
2. Switch MTU of this interface in a loop

[root@host ~]# cat repro.sh

IF=enp2s0f0v0

iperf3 -c 192.168.0.1 -t 600 --logfile /dev/null &
sleep 2

while :; do
        for i in 1280 1500 2000 900 ; do
                ip link set $IF mtu $i
                sleep 2
        done
done
[root@host ~]# ./repro.sh
