New Revision: 226469
URL: http://svn.freebsd.org/changeset/base/226469

Log:
  Don't enable the PHY radar errors in calcrxfilter.
  That way the radar errors aren't enabled prematurely.
  
  A DFS tester has reported that radar events are reported
  during channel scanning, before DFS is actually enabled.
