[dpdk-dev] [PATCH 2/6] i40e: Add permenant mac address into mac list

[Chen Jing D(Mark)]

From: "Chen Jing D(Mark)" <jing.d.chen at intel.com>

In old firmware versions, the default mac vlan filter setting is
not the one that we expected, so we'll try to remove it and add
new one to change default setting. After firmware updated, it
change default setting to the one that we expected and don't
allow to remove the setting. In this case, we should add the
perenant mac address into mac list and then return.
