From: Beilei Xing Date: Fri, 6 Jan 2017 05:27:10 +0000 (+0800) Subject: net/i40e: parse flow director filter X-Git-Tag: spdx-start~4859 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=7d83c152a207;p=dpdk.git net/i40e: parse flow director filter This patch adds i40e_flow_parse_fdir_filter to check if a rule is a flow director rule according to the flow pattern, and the function also gets the flow director info.
