I wrote this back in 2010 as my first driver project.
Reasons to remove it:
* The license is GPL
* Current WiMAX hardware is generally WIFI based.
* It controlled the hardware, but never worked
for network access since we need SSL certs and stuff
which vendors weren't too open with.
* WiMAX kind of died (at least in the US)
I left the wwan directory, it would be a nice spot
for CDMA / GSM dongle drivers.
