ath9k_rx_skb_preprocess nulls rxs and the mactime is never set again -
|
|
mactime is always 0. This causes problems in IBSS mode.
|
|
|
|
ieee80211_rx_bss_info uses mactime to decide if an IBSS merge is needed.
|
|
Without this patch the merge is triggered by each beacon received.
|
|
|
|
This can be recognized by the "beacon TSF higher than local TSF - IBSS
|
|
merge with BSSID" log message accompanying each beacon.
|
|
|
|
This problem was not completely fixed in commit
|
|
a6d2055b02dde1067075795274672720baadd3ca and is not a stable kernel fix.
|
|
It is solely intended for wireless-testing.
