From: Jingjing Wu Date: Wed, 9 Mar 2016 08:22:46 +0000 (+0800) Subject: i40e: support setting VF MAC address X-Git-Tag: spdx-start~7354 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=97ac72aa71a93d5c9bc5dc3ef1d1a324f38e61c8;p=dpdk.git i40e: support setting VF MAC address This patch implemented the ops of adding and removing mac address in i40evf driver. Functions are assigned like: .mac_addr_add = i40evf_add_mac_addr, .mac_addr_remove = i40evf_del_mac_addr, To support multiple mac addresses setting, this patch also extended the mac addresses adding and deletion when device start and stop. Each VF can have a maximum of 64 mac addresses.
