New Revision: 227380
URL: http://svn.freebsd.org/changeset/base/227380

Log:
  Disable OFDM weak signal detection by default. Leave this to be
  enabled if required by STA operation.
  
  This quietens a lot of OFDM errors seen in hostap mode, where
  there are no beacon RSSI levels to tune the dynamic range of the
  baseband.
  
  This may reduce reception range at the fringes, but does increase
  stability.
