The brcmsmac driver has been tested on a MIPS platform by Jonas Gorski
although only in STA mode (on a bcm63xx). Not having AP mode has been
explained in other emails.

Also we fully intend to transition to BCMA but that would also be new
feature added. Having AP mode and BCMA would enable you guys for using
it in the embedded targets, right?

It never hurts to look ahead. Both drivers have their use in the linux
tree and we should align which driver is doing what. Apparently we should
have yelled really hard when b43 was adding bcma support, because then
it snatched the chipsets we support as well. You learn your lessons the
hard way in Linux land, or so it seems ;-)
