Don't think 802.11, think physical layer.  The code comes from bsd and was 
brought over to improve code sharing.  I'd argue that Linux would benefit 
from something like this but then I'd be labeled as BSD-oriented... :)

ieee80211com is a private data structure.  The management api exposed on many 
systems is done through if_media (i.e. ifconfig groks if_media).
