Subject: [PATCH net-next 0/3] Introduce and use netif_xmit_timeout_ms() helper

Hi,

This series by Shahar introduces a new helper function
netif_xmit_timeout_ms() to check if a TX queue has timed out and report
the timeout duration.

Replace open-coded timeout checks in dev_watchdog() and the hns3 driver
with the new helper.

For mlx5e, refine the TX timeout recovery flow to act only on SQs whose
transmit timestamp indicates an actual timeout, as determined by the
helper. This prevents unnecessary channel reopen events caused by
attempting recovery on queues that are merely stopped but not truly
timed out.

Regards,
Tariq
