- 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.
