From c82c4a80bbb9c8ffa1d783070a8caa37f2db45b6 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 18 Jul 2012 13:31:31 +0200 Subject: mac80211: split aggregation stop by reason The initiator/tx doesn't really identify why an aggregation session is stopped, give a reason for stopping that more clearly identifies what's going on. This will help tell the driver clearly what is expected of it.
