[dpdk-dev] [PATCH v2 3/6] net/i40e: finish integration FDIR with generic flow API

Beilei Xing beilei.xing at intel.com
Thu Sep 7 13:21:00 CEST 2017


rte_eth_fdir_* structures are still used in FDIR functions.
This patch adds i40e private FDIR related structures and
functions to finish integration FDIR with generic flow API.
