From: Shaopeng He Date: Thu, 18 Jun 2015 07:21:20 +0000 (+0800) Subject: fm10k: add mac filtering X-Git-Tag: spdx-start~9018 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=f28dd9f43b2df232b2a8f88a0ee3ee7163efbe01;p=dpdk.git fm10k: add mac filtering MAC filter function was newly added, each PF and VF can have up to 64 MAC addresses. VF filter needs support from PF host, which is not available now.
