+Subject: [PATCH 16/49] iwlagn: fix TID use bug
+
+commit 9a215e40d70ae63762963ab3ccc7f31dd966dc6a upstream.
+
+The driver everywhere uses max TID count as 9,
+which is wrong, it should be 8.
+
+I think the reason it uses 9 here is off-by-one
+confusion by whoever wrote this. We do use the
+value IWL_MAX_TID_COUNT for "not QoS/no TID"
+but that is completely correct even if it is 8
+and not 9 since 0-7 are only valid.
+
+As a side effect, this fixes the following bug:
+
+ Open BA session requested for 00:23:cd:16:8a:7e tid 8
+ ------------[ cut here ]------------
+ kernel BUG at drivers/net/wireless/iwlwifi/iwl-trans-pcie-int.h:350!
+ ...
+
+when you do
+echo "tx start 8" > /sys/kernel/debug/ieee80211/*/*/*/*/agg_status
