Subject: [dpdk-dev] [PATCH v6] net/iavf: support outer IP hash for no inner GTPU
Date: Tue, 15 Sep 2020 10:43:44 +0800 [thread overview]
Message-ID: <20200915024344.31056-1-alvinx.zhang@intel.com> (raw)
In-Reply-To: <20200914090316.49740-1-alvinx.zhang@intel.com>
From: Alvin Zhang <alvinx.zhang@intel.com>
Outer IP hash can be configured as input sets for no inner GTPU packets.
Signed-off-by: Alvin Zhang <alvinx.zhang@intel.com>
V2: Modify codes according to comments.
V3: Refact all codes.
V4: Fix compatibility issues.
V5, V6: Modify codes according to comments.
