Subject: [dpdk-dev] [PATCH v2 3/4] net/iavf: support AVF RSS for GRE tunnel packet
Date: Wed,  2 Jun 2021 10:24:41 +0800	[thread overview]
Message-ID: <20210602022442.264961-4-wenjun1.wu@intel.com> (raw)
In-Reply-To: <20210602022442.264961-1-wenjun1.wu@intel.com>

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