  SVN rev 220324 on 2011-04-04 14:52:31Z by adrian
  
  Add a HAL capability bit for supporting self-linked RX descriptors and disable it for the 11n chipsets.
  
  From the ath9k source:
  
  ==
  
  11N: we can no longer afford to self link the last descriptor.
  MAC acknowledges BA status as long as it copies frames to host
  buffer (or rx fifo). This can incorrectly acknowledge packets
  to a sender if last desc is self-linked.
  
  ==
  
  Since this is useful for pre-AR5416 chips that communicate PHY errors
  via error frames rather than by on-chip counters, leave the support
  in there, but disable it for AR5416 and later.
