OK, that makes sense. Hmm, do we actually want to be using seperate
interfaces for this? I'm sure it's very useful in some applications,
but if the real point is to get packets on the wire with the priority
tags, won't IPFW, PF, or maybe even the application be the best place
for this tagging rather then effectivly using the source address to set
it? Again, I'm not familiar with the way 802.1p is intended to work, so
this may be a dumb question.
Any statement of the form "X is the one, true Y" is FALSE.
