> Subject: [PATCH 20.11] regex/mlx5: support timestamp format
>
> [ 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.
