Subject: [dpdk-stable] [PATCH v2] net/i40e: fix IPv6 fragment RSS offload type in flow
Date: Tue, 19 Oct 2021 09:53:48 +0800 [thread overview]
Message-ID: <20211019015348.13456-1-alvinx.zhang@intel.com> (raw)
In-Reply-To: <20211012083932.1428-1-alvinx.zhang@intel.com>
To keep flow format uniform with ice, this patch adds support for
this RSS rule:
flow create 0 ingress pattern eth / ipv6 / ipv6_frag_ext / end \
actions rss types ipv6-frag end queues end queues end / end
Fixes: ef4c16fd9148 ("net/i40e: refactor RSS flow")
Cc: stable@dpdk.org

v2: Update the flow pattern, the previous is "eth / ipv6_frag_ext",
now is "eth / ipv6 / ipv6_frag_ext"
