Subject: [dpdk-dev] [PATCH v6 06/22] i40e: implement operations to add/delete flow director
Date: Fri, 21 Nov 2014 08:46:40 +0800 [thread overview]
Message-ID: <1416530816-2159-7-git-send-email-jingjing.wu@intel.com> (raw)
In-Reply-To: <1416530816-2159-1-git-send-email-jingjing.wu@intel.com>
deal with two operations for flow director
- RTE_ETH_FILTER_ADD
- RTE_ETH_FILTER_DELETE
encode the flow inputs to programming packet
sent the packet to filter programming queue and check status on the status report queue
