Wow, that is the right driver...  haven't seen a driver for the 8335
before, but there it is, and it's GPL too.  Got the firmware too, which
I also haven't seen separately.

The path forward with this is to port the support for the hardware over
to mwl8k since the firmware interface is almost the same.

That said, the only reason I chose that as the path forward was that we
couldn't make any progress with the standalone driver, and figured that
Marvell's driver would actually work where mrv8k didn't.  I still think
it makes sense to use the same driver core for both but if that turns
out to be too hard, we can just do a mac80211 port for this.
