I don't see this yet on wireless-testing but it is on 2.6.32.
I backported this as follows. I'll push this out shortly.

From: Luis R. Rodriguez <lrodriguez@atheros.com>
Subject: [PATCH] Fix compilation against for 2.6.32 changes

2.6.32 added SET_NETDEV_DEVTYPE() and netdev_tx

Argh, I see what you are getting at: codes that emulates "API changes
between 2.6.(x-1) and 2.6.(x)" go into file
compat/compat-2.6.(x).{h,c} .
The 'compatibility code for new kernel' wording wasn't too obvious :-).
