vlan panic in -CURRENT

[Kevin Day]

This crashes -CURRENT (from a couple of days ago) for me:

ifconfig vlan0 create
ifconfig vlan0 vlan 2 vlandev fxp0
ifconfig vlan0 up

(immediate trap 12/page fault while in kernel mode crash)

BUT, if I manually bring up fxp0 first, everything is fine.

ifconfig fxp0 up
ifconfig vlan0 create
ifconfig vlan0 vlan 2 vlandev fxp0
ifconfig vlan0 up

I don't have a crash dump since I don't have enough space on this 
drive. but this should be pretty easy to reproduce. If this isn't 
reproducible by whoever wants to look at this, I'm happy to get a 
backtrace through some other means. I'm using a stock GENERIC kernel, 
except I've added bridging and ipfw.

Sorry if this has already  been reported, but I don't see anything in 
gnats or the mailing lists about it.
