Are you aware, that b43's code comes from RE efforts and PHY part is
mostly identical to brcmsmac/wl's one?
We have the same functions, conditions, operations here. Sometimes
called in a different way, sometimes we have different code
structures, but generally code is the same.
So I still don't see the advantages of using brcmsmac instead of b43.

I'm glad you're so proud of yours flexible API, but b43 has the same
implemented since 2008. You can see we've just easily added support
for HT-PHY using our API and I'm working on LCN-PHY right now (without
modifying the API).
We would like to have b43 supported by Broadcom. It sounds much
better, I've shown you a lot of advantages of such a choice. Switching
to brcmsmac on the other hand needs a lot of work and improvements.
