Allowing non-BE queue marking +violates that assumption and txq->ac == skb_queue_mapping is no longer +guaranteed. This can cause issues with queue handling in the driver and +also causes issues with the recent ATF change, resulting in an AQL +underflow warning. + +Cc: stable@vger.kernel.org +Signed-off-by: Felix Fietkau <nbd@nbd.name> +--- + +--- a/net/mac80211/wme.c ++++ b/net/mac80211/wme.c +@@ -147,8 +147,8 @@ u16 __ieee80211_select_queue(struct ieee + bool qos; + + /* all mesh/ocb stations are required to support WME */ +- if (sdata->vif.type == NL80211_IFTYPE_MESH_POINT || +- sdata->vif.type == NL80211_IFTYPE_OCB) ++ if (sta && (sdata->vif.type == NL80211_IFTYPE_MESH_POINT || ++ sdata->vif.type == NL80211_IFTYPE_OCB)) + qos = true; + else if (sta) + qos = sta->sta.wme; |
