Subject: [dpdk-dev] [PATCH v1 2/2] net/ice: support inner/outer L2/L3 field for FDIR
Date: Mon, 28 Sep 2020 14:31:46 +0800
Message-ID: <20200928063146.668003-3-zhirun.yan@intel.com> (raw)
In-Reply-To: <20200928063146.668003-1-zhirun.yan@intel.com>

Distinguish inner/outer fields for parse pattern. So FDIR for tunnel
can be more flexible. Enable VXLAN inner/outer L3/L4 different fields
for FDIR.
