Yes, the outgoing packets are tagged with specified priority. Then next
device (Cisco Catalyst for example) will assign traffic to different
queues according to 802.1p header information. The only thing (IMHO)
that may be coded for FreeBSD is to allow PF & IPFW assign packets to
ALTQ or DUMMYNET according 802.1p information.
