There are other bugs, yes. I'll do some more digging and submit
follow-up patches, including for the rts_rate selection.

I've tested this on BCM4321 on FreeBSD; it came up in a code review of
b43 whilst I was learning about the driver/hardware. I've tested the
change on FreeBSD and it works correctly. I'll setup a separate PC
linux environment next week to test things on.
