That way we can expose the needed stack and regulatory changes to a wider audience and shake out what I'm sure are a lot of weird bugs before we start trying to tackle many more drivers and 11ax/11ad. My TODO list on my ath10k fork is actually getting close to done, at least for the QCA9880 chip (the first generation one.) Geramy and BZ have been great in finding issues and poking at solutions. There are only a few more big TODO items before I start on the "remove the dead code" and "fix the left over linux-y locking issues" portion of this port. There are also issues with the later QCA6174 chips and QCA9888 (4x4, called beeliner) which I need to shake out, but that shouldn't stop it landing in the tree for some further testing by others. -adrian
