Fix this by only bypassing reordering for packets with no-ack policy Signed-off-by: Felix Fietkau Link: https://lore.kernel.org/r/20220420105038.36443-1-nbd@nbd.name Signed-off-by: Johannes Berg --- diff --git a/net/mac80211/rx.c b/net/mac80211/rx.c index beb6b92eb7804..88d797fa82ff6 100644 --- a/net/mac80211/rx.c +++ b/net/mac80211/rx.c @@ -1405,8 +1405,7 @@ static void ieee80211_rx_reorder_ampdu(struct ieee80211_rx_data *rx, goto dont_reorder; /* not part of a BA session */ - if (ack_policy != IEEE80211_QOS_CTL_ACK_POLICY_BLOCKACK && - ack_policy != IEEE80211_QOS_CTL_ACK_POLICY_NORMAL) + if (ack_policy == IEEE80211_QOS_CTL_ACK_POLICY_NOACK) goto dont_reorder; /* new, potentially un-ordered, ampdu frame - process it */
