New Revision: 264901
URL: http://svnweb.freebsd.org/changeset/base/264901

Log:
  Modify the ioctl path to support querying things if the vap state is
  SLEEP rather than RUN.
  
  Without this things like 'ifconfig wlan0 list sta' don't work when the
  NIC is power save.
  
  Tested:
  
  * AR5212, STA mode (with powersave)
  * AR5416, STA mode (with powersave)
