To fix that, AC queue can directly be infered from skb->priority -which has been extracted from QOS info (see ieee80211_parse_qos()). - -Second problem is the value of queue_mapping set on forwarded mesh -frames via skb_set_queue_mapping() is not the AC of the packet but a -hardware queue index. This may or may not work depending on AC to HW -queue mapping which is driver specific. - -Both of these issues lead to improper AC selection while forwarding -mesh packets but more importantly due to improper airtime accounting -(which is done on a per STA, per AC basis) caused traffic stall with -the introduction of AQL. - -Fixes: cf44012810cc ("mac80211: fix unnecessary frame drops in mesh fwding") -Fixes: d3c1597b8d1b ("mac80211: fix forwarded mesh frame queue mapping") -Co-developed-by: Remi Pommarel <repk@triplefau.lt> -Signed-off-by: Remi Pommarel <repk@triplefau.lt> -Signed-off-by: Nicolas Escande <nico.escande@gmail.com> ---- - ---- a/net/mac80211/rx.c -+++ b/net/mac80211/rx.c -@@ -2921,13 +2921,13 @@ ieee80211_rx_h_mesh_fwding(struct ieee80 - ether_addr_equal(sdata->vif.addr, hdr->addr3)) - return RX_CONTINUE; - -- ac = ieee80211_select_queue_80211(sdata, skb, hdr); -+ ac = ieee802_1d_to_ac[skb->priority]; - q = sdata->vif.hw_queue[ac]; - if (ieee80211_queue_stopped(&local->hw, q)) { - IEEE80211_IFSTA_MESH_CTR_INC(ifmsh, dropped_frames_congestion); - return RX_DROP_MONITOR; - } -- skb_set_queue_mapping(skb, q); -+ skb_set_queue_mapping(skb, ac); - - if (!--mesh_hdr->ttl) { - if (!is_multicast_ether_addr(hdr->addr1)) |
