From 85ad181ea78861f69b007599cec9e6ba33fcdf8a Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 10 Jun 2010 10:21:49 +0200 Subject: mac80211: allow drivers to sleep in ampdu_action Allow drivers to sleep, and indicate this in the documentation. ath9k has some locking I don't understand, so keep it safe and disable BHs in it, all other drivers look fine with the context change.
