Subject: net/mlx5e: Increase Async ICO SQ size
Patch-mainline: v5.9-rc1
Git-commit: c5607360ec4ea5d0c955de501b9eeb04fa2465d0
References: jsc#SLE-15172

Resync communication with HW for kTLS RX is done via the
async ICOSQs.
kTLS RX resync requests might come in bursts. To improve the
success chances for such bursts, use a larger ICOSQ.
