It looks like that could work, but it seems a lot easier to probe
network devices via normal manner, and then check if I can just
open and read /sys/class/net/[dev-name]/phy80211/name

I can do that easily from within a C/C++ program, where as
doing system calls and grabbing standard output is more of
a pain (and more overhead).

But, if you don't want to add my patch, it's not a big deal.

Thanks,
Ben
