= 1, when packets are output on the port, the
switch will remove 802.1p/q tags from packets
with 802.1p/q tags when received. The switch will
not modify packets received without tags.
= 0, disable tag removal
= 1, the port output queue is split into high and
low priority queues.
= 0, single output queue on the port. There is no
