Subject: [dpdk-stable] [DPDK] net/ice: fix flow rule checking
Date: Wed, 27 Jan 2021 07:42:44 +0000	[thread overview]
Message-ID: <20210127074244.43780-1-yuanx.wang@intel.com> (raw)

Currently, when the RSS rule set to l4-src-only and l4-dst-only,
the hash value is different while the ingress packets
have same L4 parameters.

This patch keeps the hash value consistent in above situation.

Fixes: 38d632cbdc88 ("net/ice: refactor PF RSS")
Fixes: 0b952714e9c1 ("net/ice: refactor PF hash flow")
Cc: stable@dpdk.org
