Subject: [net 06/12] net/mlx5: DR, Don't use SW steering when RoCE is not supported
Date: Wed, 9 Jun 2021 17:21:49 -0700 [thread overview]
Message-ID: <20210610002155.196735-7-saeed@kernel.org> (raw)
In-Reply-To: <20210610002155.196735-1-saeed@kernel.org>
From: Maor Gottlieb <maorg@nvidia.com>
SW steering uses RC QP to write/read to/from ICM, hence it's not
supported when RoCE is not supported as well.
Fixes: 70605ea545e8 ("net/mlx5: DR, Expose APIs for direct rule managing")
