The VLAN patches allow you to map a skb->priority into a VLAN priority.
So, all you have to do is figure out how to map your process into a
skb->priority. I haven't ever tried that, but I'm pretty sure it's
an IOCTL option that you can set on a socket. There may be some more
general ways to affect priority too...

Hopefully, someone on the linux-net group has a better idea...
