[5/5] compress/mlx5: add timestamp format support
Checks
Commit Message
This patch add support for the timestamp format settings for
the receive and send queues. If the firmware version x.30.256
or above is installed and the NIC timestamps are configured
with the real-time format, the default zero values for new
added values cause the queue creation reject. The patch
queries the timestamp formats supported by the hardware and
sets the configuration values in queue context accordingly.
Fixes: 8619fcd5161b ("compress/mlx5: support queue pair operations")
