Sure, but the rate algorithms may not optimize perfectly for every
user.  If packet loss is very painful (maybe for VOIP?), then
it may be worth running at a lower rate for less packet loss?

Why did we allow setting rates in the a/b/g modes (even if not
through hostap) ?

Would it help if I made it something that is only compiled in when
the user selects the option in the config file?

Thanks,
