liquidio: implement vlan filter enable and disable
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.
