This new driver will be moved to drivers/net/wireless for 3.15, Larry
has a real port of it to the proper apis and the like, cleaning up these
types of issues already. It didn't make 3.14, which is why I added the
staging version for now (i.e. I want the hardware I have to work...)

Larry is the one who could answer for the remaining realtek drivers, and
the "changes don't flow back" issues.
