Agreed. But again, that should be built into mac80211, if we want to work
around issues caused by lack of module autoloading. And to me it looks like
'rc80211_none' implies yet another 'real' rate control algorithm.

I propose to just replace a few lines of code in mac80211 in order to look
for the lowest available rate and set it instead of failing. mac80211 should
[1] correctly deal with forced rates, so that would be everything we need.

[1] I know it doesn't right now. That should be fixed first anyway.
