Actually please print parameters from below patch. I think ba_size should be based on per TID buf_size instead of ampdu_factor, in case STA has buf size different for some TIDs. Also adding Felix to cc since my orginal patch: http://marc.info/?l=linux-wireless&m=147809595316289&w=2 was shamelessly stolen from mt76 driver. Perhaps Felix could provide us some expertise.
