From 044423c4db97ca1911d0dcd06bc21f3fe84ed8c7 Mon Sep 17 00:00:00 2001 From: Viacheslav Ovsiienko Date: Sun, 14 Mar 2021 12:13:00 +0000 Subject: [PATCH] vdpa/mlx5: support timestamp format 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.
