The new band API is really really needed. I already have dozens of FIXMEs
in b43 that will automatically go away once the mac80211 API is changed.
Lots of FIXMEs will be added if this is not merged.

Please apply this patch and apply fixes inside of the 2.6.25 development
cycle. We are in a _development_ kernel. Kernels _do_ break in development
stages. That is the whole reason why development kernels exist.

So if we push this patch to 2.6.26 another bug appears. Should we push
it to 2.6.27 then instead of simply fixing it in the development cycle?

Besides that, _nobody_ will test the patch, if it's not applied to your
tree. So the situation will not be better when you apply it in the
next development cycle.

And for users complaining about a development kernel being unusable, well,
what to say about them? I'd say the right answer would be: Go and use
a stable kernel!

Please realize that delaying this patch means increasing the pain for
driver developers that need this patch for another 80-100 days.
