Async ICOSQ is longer than the normal ICOSQ, and the CQ size must be the same as the size of the corresponding SQ, but due to this bug, the CQ of async ICOSQ was much shorter than async ICOSQ itself. It led to overflows of the CQ with such messages in dmesg, in particular, when running multiple kTLS-offloaded streams: mlx5_core 0000:08:00.0: cq_err_event_notifier:529:(pid 9422): CQ error on CQN 0x406, syndrome 0x1 mlx5_core 0000:08:00.0 eth2: mlx5e_cq_error_event: cqn=0x000406 event=0x04 This commit fixes the issue by using the corresponding parameters for ICOSQ and async ICOSQ.
