[dpdk-stable] [PATCH 20.11] regex/mlx5: support timestamp format

[Viacheslav Ovsiienko]

[ upstream commit dd25bd201d18729b883acc4d4120a5e751807f5f ]

This patch adds support for the timestamp format settings for
the receive and send queues. If the firmware version x.30.1000
or above is installed and the NIC timestamps are configured
with the real-time format, the default zero values for newly
added fields cause the queue creation to fail.

The patch queries the timestamp formats supported by the hardware
and sets the configuration values in queue context accordingly.

Fixes: 92f2c6a30fe0 ("regex/mlx5: add send queue")
