Subject: [dpdk-dev] [PATCH] net/mlx5: allow copy from one tag to another
Date: Tue, 25 May 2021 20:14:14 +0300	[thread overview]
Message-ID: <20210525171414.1155872-1-akozyrev@nvidia.com> (raw)

The modify field implementation in mlx5 driver has a check to
prevent a copy from a field to the same field. But the level
is not taken into account which prevents a copy from different
tags. Check the level and allow a copy from one tag to another.

Fixes: 641dbe4fb05 ("net/mlx5: support modify field flow action")
Cc: stable@dpdk.org
