de(4) NIC change in 3.9 release

[Darren Spiteri]

I updated my i386 3.8 system to 3.9 and noticed that my ALTQ rules
wouldn't load on de0 de(4), giving error:
        pfctl: de0: driver does not support altq

ALTQ worked before and I can't see any explicit notice of was this
changed on purpose. Has anyone else come across this?
