Hi Marcin,

Since v3 has no code changes from v2, please feel free to add:

Tested-by: Jerome Tollet <jtollet@cisco.com>

My ConnectX-5 test results are in my earlier reply:
https://lists.openwall.net/netdev/2026/10/30/342

With both earlier mlx5e refill fixes present, the unpatched kernel still
showed RX frame ownership errors with striding RQ, with need_wakeup both
enabled and disabled. The same tests passed with your v2 patch applied.

I have retained the standalone libxsk reproducer used for these tests
and can share it if useful.

Thanks,
Jerome
