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. If Double VLAN Mode is enabled then an explicit VLAN 0 + VLAN TPID filter needs to be added to allow VLAN 0 priority tagged traffic in DVM, since the VLAN TPID is part of filtering.
