What's the difference between that and IBSS? I : haven't found this term in the standard. 'ibss-master' is the master ibss you need one of these. 'ibss' is for all the other nodes on the network.

On one machine (running CURRENT from 12 December : 2001), it only shows the last machine contacted, but on a more recent : CURRENT it shows at least two of them. Is this a difference in the : cards or in CURRENT? It does it at the mac level, so only those mac addresses that you are talking to will have entries.
