wds ap:
config wifi-device 'radio0'

option hwmode '11g'

wds station:
config wifi-device 'radio0'

When the station break off, ping can not reach ap. wifi still
connect. kernel have no error info. iwinfo signal still change.
ap with the other station still alive.
Use wpa_cli scan command, will awake station, and ping alive.
wifi command also work.
/proc/interrupts ath9k still alive.

All:
Add some debug info in mac80211, i can get data packet in
__ieee80211_rx_handle_packet
4053 if (ieee80211_is_mgmt(fc)) {
4054 mac80211_dbg(local, RX, "mac80211 mgmt
packet\n");
4055 /* drop frame if too short for header */
4083 } else if (ieee80211_is_data(fc)) {
4084 mac80211_dbg(local, RX, "mac80211 data
packet\n");
4085 struct sta_info *sta, *prev_sta;
with ping packet log:
[ 8996.617367] mac80211 data packet
[ 8996.622783] mac80211 mgmt packet
[ 8996.725036] mac80211 mgmt packet
[ 8996.820829] mac80211 data packet
[ 8996.829383] mac80211 mgmt packet
[ 8996.931682] mac80211 mgmt packet
[ 8997.033052] mac80211 mgmt packet
[ 8997.135956] mac80211 mgmt packet
And station will deauth from ap with PRE_AUTH_NOT_VALID:
[ 8998.621385] wlan0: deauthenticated from c8:ee:a6:2d:cc:6c (Reason:
2=3DPREV_AUTH_NOT_VALID)
[ 8998.629537] br-lan: port 2(wlan0) entered disabled state
[ 9003.635631] wlan0: authenticate with c8:ee:a6:2d:cc:6c
[ 9003.651230] wlan0: send auth to c8:ee:a6:2d:cc:6c (try 1/3)
[ 9003.670365] wlan0: associate with c8:ee:a6:2d:cc:6c (try 1/3)
[ 9003.681735] wlan0: RX AssocResp from c8:ee:a6:2d:cc:6c (capab=3D0x431
status=3D0 aid=3D1)
[ 9003.815829] br-lan: port 2(wlan0) entered forwarding state
I think some bug in auth cause data packet drop.

Hi,
Why ap send deauth packet?
I grep the source find deauth in ieee80211_rx_mgmt_deauth.

I catched the bug position:
in mac80211 ieee80211_sta_manage_reorder_buf function:
/* frame with out of date sequence number */
if (ieee80211_sn_less(mpdu_seq_num, head_seq_num)) {
ieee80211_sn_less will check seq_num. But in ath9k wds mode, I found
some time mpdu_seq_num will less than head_seq_num. Then all recvieve
data packet will drop.
my log:
[ 8137.201050] mac80211 with out of date seq number: 3843 3890
