change detection of wireless, add net.irda and net.80211control

Changed the detection of wireless network devices. The currently used
proc file is/become IIRC deprecated. I change the detection to check
for /sys/class/net/*/wireless (which was already in the code but commented
out).

I added also some code and spec information for IrDA net devices (net.irda)
and ARPHRD_IEEE80211* (wireless lan control-) devices (net.80211control).
