| Subject: mac80211: minstrel_ht: set default tx aggregation timeout to 0 |
| |
| From: Felix Fietkau <nbd@openwrt.org> |
| |
| commit 7a36b930e6ed4702c866dc74a5ad07318a57c688 upstream. |
| |
| 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. |
