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.
