In this case you might have a different rate for every node in your network. Looking up just "sdata->u.sta.bssid" is insufficient because the BSSID of an IBSS network is not a real MAC address (after all, there is no AP). I would very much like an official way to enumerate the current rates for all known stations in an IBSS network. This information would be useful for AdHoc routing: Currently most approaches use packet loss to weight different links. In this case a link might look better than it actually is, because rate control already lowered the current rate to a level where no packet loss occured whereas another link with higher data rate looks bad because it drops a packet now and than. Is there a way to get this information? -- Regards Joerg __________________________________ Yahoo!
