atheros hardware has a problem with the rx timestamp of some IBSS beacons when they caused a TSF update (they have the same BSSID). the rx timestamp is wrong especially if the beacon frames get bigger than 78 byte (at least on AR5213 and AR5414 hardware). in that case ath5k_extend_tsf() will assume a rs_tstamp overflow and give us a timestamp too far in the past which will cause mac80211 to merge IBSS on every beacon (which is not necessary since the BSSID already matches). but in this case we know that the HW must have synced to the beacons TSF and the rx timestamp must be later than that so we can adjust mactime accordingly. also rename the function to ath5k_check_ibss_tsf() and change comments, since "hw merge" is better described as a TSF update. drivers/net/wireless/ath5k/base.c: Changes-licensed-under: 3-Clause-BSD Signed-off-by: Bruno Randolf <bruno@thinktube.com> Signed-off-by: John W.
