Hi,

The aggregate size is determined by a couple of places in
ath9k/xmit.c. The trouble is the code doesn't "pause" and wait for
frames to appear before aggregating them, so you'll have to add some
logic to mac80211 and ath9k to do that. Otherwise all you can do is
aggregate UP to a certain level, not ALWAYS that amount.
