Subject: [dpdk-dev] [PATCH 2/3] net/ice/base: add support for L2TP on switch
Date: Fri, 17 Apr 2020 16:26:16 +0800 [thread overview]
Message-ID: <20200417082617.33361-3-wei.zhao1@intel.com> (raw)
In-Reply-To: <20200417082617.33361-1-wei.zhao1@intel.com>
Add dummy packet and tunnel type to support
L2TP on switch, now we can use session id as
input set for swicth rule.
Signed-off-by: Wei Zhao <wei.zhao1@intel.com>
