[dpdk-dev] [PATCH] fm10k: fix PF/VF MAC address register and clean up bug

[Shaopeng He <shaopeng.he@intel.com>]

MAC address with fixed VLAN 0 was removed. VF MAC/VLAN filter was enabled
for the default value. Removed all VLAN and MAC address table entries when
the system(e.g. testpmd) was closed.
