Subject: [dpdk-dev] [PATCH] net/mlx5: fix RSS validation function
Date: Thu, 11 Apr 2019 09:06:03 +0000 [thread overview]
Message-ID: <1554973447-3009-1-git-send-email-orika@mellanox.com> (raw)
The RSS validation function was missing the verifcation that
if RSS is requested on inner packet, the flow must have tunnel data.
Fixes: 23c1d42c7138 ("net/mlx5: split flow validation to dedicated function")
Cc: stable@dpdk.org
