Drop Untag:
Drop untagged frame. You can configure a given port to accept all frames
(Tagged and Untagged) or just receive tagged frame. If the former is the
case, then the packets with tagged or untagged will be processed. If the
later is the case, only the packets carrying VLAN tag will be processed,
the rest packets will be discarded.
