Subject: RE: [PATCH V6] mac80211: Add support for SIOCGIWRATE ioctl to provide rate information
Date: Wed, 23 May 2007 02:49:08 -0700 (PDT) [thread overview]
Message-ID: <569491.18256.qm@web51409.mail.re2.yahoo.com> (raw)
Hello all,
what does SIOCGIWRATE do for IBSS networks? 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?

Joerg
