Subject: [PATCH v5 5/6] net/iavf: support L2TPv2 for AVF HASH
Date: Wed, 9 Feb 2022 17:38:56 +0800 [thread overview]
Message-ID: <20220209093857.79364-6-jie1x.wang@intel.com> (raw)
In-Reply-To: <20220209093857.79364-1-jie1x.wang@intel.com>
Add support for PPP over L2TPv2 over UDP protocol and L2TPv2
protocol RSS hash based on outer MAC src address and L2TPv2
session ID.
Patterns are listed below:
eth/ipv4/udp/l2tpv2
eth/ipv4/udp/l2tpv2/ppp
eth/ipv6/udp/l2tpv2
eth/ipv6/udp/l2tpv2/ppp
