I've only taken a quick look and I'll make specific comments to
specific patches later, but I've got to ask the question, should these
changes go into ath6kl or be a new driver?

Just because the number starts with 6000 doesn't mean it's a ath6kl
chip. The 10k series chips all start with 9000 for example, but they
rate their own driver.

You state that all of the underpinnings of the communication with the
chip are totally different:
* Doesn't use WMI
* Different mailboxing
* Different HTC layer

If all of the commands and all of the communication layers to the chip
are totally different, then perhaps it isn't an ath6kl chip. So if
it's largely similar, then OK, but seems to me with the changes you're
saying above, it's mostly different.

I'm saying all that without any knowledge of this chip. My experience
is limited to various versions of the 6003 and 6004 chips.

Just trying to stimulate discussion here.
