Subject: [dpdk-stable] [PATCH 4/5] regex/mlx5: add timestamp format support
Date: Sun,  7 Mar 2021 10:02:50 +0000
Message-ID: <20210307100251.22538-5-viacheslavo@nvidia.com> (raw)
In-Reply-To: <20210307100251.22538-1-viacheslavo@nvidia.com>

This patch adds 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: 92f2c6a30fe0 ("regex/mlx5: add send queue")
Cc: stable@dpdk.org
