dyoung 595c6d88b2 Add support for Prism monitor mode. From Kevin Lahey 
<kml@patheticgeek.net>.

This patch does NOT add monitor mode support for the Lucent radios.

awi(4) was only modified for compatibility with the new mediaopt.
It does NOT support monitor mode.

Tested by Kevin, Daniel Carosone, and I.
