Device wlan0 has different MAC address than expected, ignoring.

[Kim Lux]

I just got it working and I'm not sure why.

I pulled "alias wlan0 ndiswrapper" out of modprobe.conf

I removed ifcfg-wlan0.  I uninstalled the broadcom driver. I rebooted
and I installed everything again.  It works. 

I think that leaving the alias in modprobe caused the problem. Now
everything works including probing the MAC.
