The mactime is always set to 0. I encountered the problem in IBSS mode.
In ieee80211_rx_bss_info (net/mac80211/ibss.c) the mactime is used to
trigger an IBSS merge. At the moment the merge is always triggered.

I got the "beacon TSF higher than local TSF - IBSS merge with BSSID" log
message with every beacon and so recognized this odd behaviour.

I think this has to be fixed and at least influences IBSS mode negatively.
