New Revision: 343974
URL: https://svnweb.freebsd.org/changeset/base/343974

Log:
  MFC r343698, r343700:
  ifconfig(8): display management / multicast wlan(4) rates properly
  
  For 11n / 11ac we are still using non-11n rates for management and
  multicast traffic by default; check 'MCS rate' bit to determine how
  to print them correctly.
