Subject: [dpdk-dev] [PATCH 2/7] net/ice: configure HW FDIR rule
Date: Tue, 24 Sep 2019 10:10:35 +0800 [thread overview]
Message-ID: <20190924021040.77648-3-yahui.cao@intel.com> (raw)
In-Reply-To: <20190924021040.77648-1-yahui.cao@intel.com>
From: Beilei Xing <beilei.xing@intel.com>
This patch adds a HW FDIR rule to the FDIR HW table
without adding a FDIR filter.
