Subject: net/mlx5e: xsk: Use mlx5e_trigger_napi_icosq for XSK wakeup
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d54d7194ba48e074d4d51580753d3a396b82aecf;p=linux.git

net/mlx5e: xsk: Use mlx5e_trigger_napi_icosq for XSK wakeup

mlx5e_xsk_wakeup triggers an IRQ by posting a NOP to async_icosq, taking
a spinlock to protect from concurrent access. There is already a
function that does the same: mlx5e_trigger_napi_icosq. Use this function
in mlx5e_xsk_wakeup.
