New Revision: 251400
URL: http://svnweb.freebsd.org/changeset/base/251400

Log:
  Add a new capability flag to announce that the chip implements LNA mixing
  for the RX path.
  
  This is different to the div comb HAL flag, that says it actually
  can use this for RX diversity (the "slow" diversity path implemented
  but disabled in the AR9285 HAL code.)
  
  Tested:
  
  * AR9285, STA operation
