Well, everything in there has been tested (limited though, as you
yourself experienced), but it is not complete. I still have some other
patches that need some more refurbishing before I can push them.

I will push those patches that I consider "good enough" for publish to
this repo. Most likely I will rewrite/squash etc. some of it before
submitting a new RFC series.

So, there are still some additional stuff that needs to be added. In my
case I have a series of patches related to OCB (Outside the Context of a
BSS) mode of operation (since the chipset I am using is intended for
this purpose). These patches are still not complete.

Other SDIO 11ac chipsets might just need an item in the struct
ath10k_hw_params array together with some firmware files.

I actually have some patches regarding this, but they have not been
tested at all since I have not yet managed to fully configure my SDIO
chip properly so far. I must finish the OCB code I mentioned earlier and
fix another really annoying issue with a missing HTT version response
(sometimes target won't respond to the HTT version request).

Then, hopefully, I can make some TX and RX tests.

I think the HTT TX part is fairly straight forward. But the RX part is a
little bit more tricky since I am not really sure about how to interface
mac80211 in the RX path.

My work flow goes like this:

As soon as there is a new tag on the ath.git master, I rebase my stuff
on top of it and push a new branch to my repo.

I will continuously push updates to the latest branch (the branch based
on the latest ath tag).

Older branches will not be maintained.
