Well at http://people.suug.ch/~tgr/libnl/ it still only lists 1.1 but
the git repository shows a clear move to 2.0 (forget I mentioned 1.2,
that was my own tracking label).  The code had a bunch of commits in
October.  In retrospect, if I just downloaded the 1.1 tarball from that
webpage instead of using the git HEAD everything would have been fine. 
Patches can probably wait until 2.0 is officially released.

When I reboot, modprobe the driver, and do 'iwconfig wlan0 channel 9
commit' the .config callback does run.  If I leave off the 'commit' it
does not.  I'm trying to validate as many callbacks as I can before
moving on to the next step, enabling the interface.

An additional question, if I may... Is wlan0 considered a "virtual
interface" or does that term only apply to additional interfaces created
with iw?  The whole vif thing has me a little confused.

Thanks for the help.
