What about adding WMM IEs? etc. I couldn't find anything on this in the IEEE standard - it only talks about infrastructure mode, and that EDCA Parameter IEs should be adopted. (Although I doubt that's a good idea). All we want here is to locally change the parameters. Seems we are not the first ones who want to do that [1]. The WMM specification only says that no WMM IEs is in the beacon and distribution of parameters is missing, and therefore defaults are to be used. Therefore, I'd like to go for the local changes only and skip WMM IEs, adoption, etc. You have a point regarding IBSS merging - with this change, we would lose the local configuration with the merge. This could be changed for mac80211, not sure about other drivers (or if anyone actually cares). Cheers, Simon [1] http://www.uniroma2.it/didattica/TPI2/deposito/wmm.pdf [page 7, bottom]
