From: Jingjing Wu Date: Thu, 29 Jan 2015 05:29:18 +0000 (+0800) Subject: ixgbe: support new flow director masks X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=76c6f89e80d4a89f541f7625e355ad2cf3cc0737;p=dpdk.git ixgbe: support new flow director masks This patch implement the mask configuration of flow director filter, by using the mask defined in rte_fdir_conf instead of callback function fdir_set_masks.
