Um, no, the ath10k depends on a binary blob. Which has been really
irksome. I do hope they open-source the firmware so we can make
more progress on incorporating better algorithms into wifi.

It's not clear how to ensure you are buying a v2 through sites like amazon.

If you can find a good source for it let me know...
