+Subject: [PATCH] mac80211: minstrel_ht: set default tx aggregation timeout to
+ 0
+
+The value 5000 was put here with the addition of the timeout field to
+ieee80211_start_tx_ba_session. It was originally added in mac80211 to
+save resources for drivers like iwlwifi, which only supports a limited
+number of concurrent aggregation sessions.
+
+Since iwlwifi does not use minstrel_ht and other drivers don't need
+this, 0 is a better default - especially since there have been
+recent reports of aggregation setup related issues reproduced with
+ath9k. This should improve stability without causing any adverse
+effects.
