This was introduced in December 25th, 2015 after some firmware-related 
problems. I'm CC'ing Martin Blumenstingl who suggested this change.

Since then, ath10k is pulling firmware from here (unless ct firmware is used):

https://source.codeaurora.org/quic/qsdk/oss/firmware/ath10k-firmware/plain/
10.2.4/firmware-5.bin_10.2.4.97-1

However, I don't understand the numbering? 10.2.4.97 > 10.2.4.70, but you say 
10.2.4.70.42-2 is more recent? I would have assumed otherwise from the 
numbers. However, 10.2.4.70 has much more sub-revisions. Is there any document 
describing the revisions? I don't understand it at least from this wiki page 
[1].

Thanks!
