+Subject: [PATCH] mac80211: fix regression in SSN handling of addba tx
+
+Some drivers that do their own sequence number allocation (e.g. ath9k) rely
+on being able to modify params->ssn on starting tx ampdu sessions.
+This was broken by a change that modified it to use sta->tid_seq[tid] instead.
+
+Cc: stable@vger.kernel.org
+Fixes: 31d8bb4e07f8 ("mac80211: agg-tx: refactor sending addba")
+Reported-by: Eneas U de Queiroz <cotequeiroz@gmail.com>
