Centrino Advanced-N 6235 on Asus Zenbook UX32VD poor performance

[Adrian Chadd]

Yeah, the freebsd intel driver likely requires quite a bit more attention. :(

I think I have a 6235 here but I don't have an antenna connection for
it so I can test it. It's the one that's smaller than u.fl, which is
freaking annoying.

(Someone may have to send me a laptop with this NIC in it so I can fix it up..)
