Subject: [dpdk-dev] [PATCH v2 1/8] net/ice/base: fix GTP-U inner RSS IPv4 IPv6 co-exist
Date: Wed, 1 Jul 2020 13:49:44 +0800 [thread overview]
Message-ID: <20200701054951.2393-2-qi.z.zhang@intel.com> (raw)
In-Reply-To: <20200701054951.2393-1-qi.z.zhang@intel.com>
An IP header combined with GTP-U header should be regarded as
inner layer for RSS, otherwise it mess the field vector between
an IPv4 rule and IPv6 rule e.g:
testpmd> flow create 0 ingress patterh eth / ipv4 / udp / gtpu / \
gtpu_psc / ipv4 / udp / end actions rss types ipv4-udp end key_len \
0 queues end / end
testpmd> flow create 0 ingress patterh eth / ipv4 / udp / gtpu / \
gtpu_psc / ipv6 / udp / end actions rss types ipv6-udp end key_len \
0 queues end / end
Fixes: b7d34ccc47b5 ("net/ice/base: packet encapsulation for RSS")
