New Revision: 219979
URL: http://svn.freebsd.org/changeset/base/219979

Log:
  Flip ANI on for the AR5416 and later chips. I haven't verified it on
  the AR9285 so I'll leave it off for that.
  
  Ath9k sources indiciate that one of the ANI modes interferes with
  RIFS detection, so match ath9k and disable that.
