I meant board-2.bin actually:

$ md5sum QCA6174/hw2.1/board-2.bin 
11920f7c30a1b1dd009928baef1021dc  QCA6174/hw2.1/board-2.bin

This file should support your board with subsystem id 17aa:3044.

>From the logs I can't immeaditely see anything wrong, but you version of
ath10k is so old that it doesn't print the crc32 for the board file so I
can't be 100% sure. So I recommend to check the md5sum above matches
with your file.

>From a quick look I can't immediately come up what else would cause low
throughput, it would involve more detailed analysis with wireless
sniffer etc. It's a wild shot but you could always try latest ath10k
using kernel-backports:

https://wireless.wiki.kernel.org/en/users/drivers/ath10k/backports

Do note that backports project hasn't had stable updates for a long time
so use the daily releases instead:
