New Revision: 312562
URL: https://svnweb.freebsd.org/changeset/base/312562

Log:
  [ath] ensure both iv_ampdu_limit and iv_ampdu_rxmax is set.
  
  A recent change enforced the VAP limit as well as the peer limit.
  I now need to actually set iv_ampdu_limit or we don't transmit more
  than 8K sized aggregates.
  
  This restores the expected (suboptimal, but still much faster) behaviour.
  
  Tested:
  
  * AR9380, STA mode
