I hold back this patch for around a week to avoid
confusion. This is the second step of
"mac80211: Fixed BSSID handling revisited".
With it, in the situation of a strange merge to the
same BSSID (e.g. caused by a TSF overflow) only
reset_tsf() is called.
And sta_info_flush_delayed() is only called if you
change the network manually, not on an automatic
BSSID merge.
