Subject: [dpdk-dev] [PATCH v1] net/mlx5: fix RSS expansion for GTP
Date: Sun, 18 Jul 2021 14:15:04 +0300	[thread overview]
Message-ID: <20210718111504.2654396-1-lmargalit@nvidia.com> (raw)

The flow did not expand correctly when it included a GTP item.

Added GTP node to the expansion graph as possible next node
after IPv4/IPv6 UDP node.

Fixes: 592f05b29a25 ("net/mlx5: add RSS flow action")
Cc: stable@dpdk.org
