(mail@janderson.ca): remove ieee80211_ibss_merge's TSFT argument. Do the TSFT comparison in the drivers (ath, atw). Remove a lot of extraneous debug statements from ieee80211_ibss_merge. Set the ieee80211_node's state to IEEE80211_STA_BSS after it's been copied to the ic_bss, not before. In struct ieee80211_node, make the ni_tstamp field a union of a uint64_t and the 8 TSF octets so that it's easier to compare a neighbor's TSF with the local TSF. Log IBSS merges (Greg Troxel's suggestion). Also log IBSS creation. These are rare and important events that deserve to be logged.
