+Subject: [PATCH] mac80211: fix an off-by-one issue in A-MSDU
+ max_subframe computation
+
+Initialize 'n' to 2 in order to take into account also the first
+packet in the estimation of max_subframe limit for a given A-MSDU
+since frag_tail pointer is NULL when ieee80211_amsdu_aggregate
+routine analyzes the second frame.
+
+Fixes: 6e0456b54545 ("mac80211: add A-MSDU tx support")
