CT firmware supports a great deal of things, such as IBSS, tx-rate reporting,
more control over tx-buffer allocation, rate-ctrl improvements and so forth.

I have another hundred or so patches that can enable and take advantage
of this sort of thing, but in the past, there has been no desire to allow
these patches upstream, so I am trying to feed some of the least controversial
patches first in case attitudes have changed.

And, you can clone it:

git clone git://dmz2.candelatech.com/linux-4.4.dev.y

With regard to the patches in this series to dump the BSS regions and similar, I would
be happy to share my packaging script with QCA folks so they can add that info to their
own firmware. With BSS and Stack dumps, you can walk back through null-pointer exceptions
in the firmware and get a full backtrace instead of just the last call location.  This means
you can remove a huge number of ASSERTS, which frees up IRAM and overall makes the code
