New Revision: 230791
URL: http://svn.freebsd.org/changeset/base/230791

Log:
  Radar API related fixes.
  
  * For legacy NICs, the combined RSSI should be used.
    For earlier AR5416 NICs, use control chain 0 RSSI rather than combined
    RSSI.
    For AR5416 > version 2.1, use the combined RSSI again.
  
  * Add in a missing AR5212 HAL method (get11nextbusy) which may be called
    by radar code.
  
  This serves no functional change for what's currently in FreeBSD.
