Subject: liquidio: implement vlan filter enable and disable
Patch-mainline: v4.13-rc1
Git-commit: 836d57e5c08e13bb206dcd559d96ee9355e8316e
References: bsc#1067126
Add implementation to support ethtool -K ethX rx-vlan-filter on/off.
Rename OCTNET_CMD_ENABLE_VLAN_FILTER command to OCTNET_CMD_VLAN_FILTER_CTL
and add OCTNET_CMD_VLAN_FILTER_ENABLE and OCTNET_CMD_VLAN_FILTER_DISABLE
parameters so that it can be used to enable or disable the filter.
