net/mlx5e: Guarantee room for XSK wakeup NOP on async ICOSQ
[ Upstream commit 3ff3874f ] XSK wakeup flow triggers an IRQ by posting a NOP WQE and hitting the doorbell on the async ICOSQ. It maintains its state so that it doesn't issue another NOP WQE if it has an outstanding one already. For this flow to work properly, the NOP post must not fail. Make sure to reserve room for the NOP WQE in all WQE posts to the async ICOSQ. Fixes: 8d94b590 ("net/mlx5e: Turn XSK ICOSQ into a general asynchronous one") Fixes: 1182f365 ("net/mlx5e: kTLS, Add kTLS RX HW offload support") Fixes: 0419d8c9 ("net/mlx5e: kTLS, Add kTLS RX resync support") Signed-off-by: Tariq Toukan <tariqt@nvidia.com> Reviewed-by: Maxim Mikityanskiy <maximmi@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@nvidia.com> Signed-off-by: Sasha Levin <sashal@kernel.org>
