> In Double VLAN Mode, outer/single VLAN filters via ICE_SW_LKUP_VLAN are
> based on the outer/single VLAN ID + VLAN TPID.
>
> For both modes, adding a VLAN 0 + no VLAN TPID filter to handle untagged
> traffic when VLAN pruning is enabled. Also, this handles VLAN 0 priority tagged
> traffic in Single VLAN Mode, since the VLAN TPID is not part of filtering.
