Subject: [dpdk-dev] [PATCH v1 3/4] net/iavf: support AVF RSS for GTPoGRE packet
Date: Wed,  7 Jul 2021 12:57:52 +0000	[thread overview]
Message-ID: <20210707125753.1494483-4-lingyu.liu@intel.com> (raw)
In-Reply-To: <20210707125753.1494483-1-lingyu.liu@intel.com>

Support AVF RSS for inner most header of GTPoGRE packet. It supports
RSS based on inner most IP src + dst address and TCP/UDP src + dst
port.
