Subject: [net-next V2 11/13] net/mlx5: Expose ts_cqe_metadata_size2wqe_counter

From: Aya Levin <ayal@...dia.com>

Add capability field which indicates the mask for wqe_counter which
connects between loopback CQE and the original WQE. With this connection
the driver can identify lost of the loopback CQE and reply PTP
synchronization with timestamp given in the original CQE.
