  The NIC since 6DX supports multiple timestamp formats
in CQEs configured via firmware. If real time timestamp
format has been configured the correct attributes should
be specified on queue creation via DevX. These attributes
setting was missed on steering queue creation and hardware
steering initialization failed.

Fixes: 3eb748869d2d ("net/mlx5/hws: add send layer")
