Linux, apparently, does not currently support 802.1Q priority tags by 
default.  A patch was suggested to add such support, but I can't tell 
from the following thread whether it made it to general release, or when 
it did if so.

For now, I expect that you'd need to manually configure a "0" VLAN on 
interfaces attached to networks where priority tagged packets are used. 
  If that patch was accepted, it may be sufficient to simply load the 
8021q kernel module.
