ath10k and QCA3977 - random transfer rate losses

Tobias,

It seems to be like the RF tx/rx capability issue, usually due to the incorrect board file is using.

I can't find exactly the same module you've to try.
Can you help to verify this attached board-2.bin file to see if that help the issue you've?

cp board-2.bin.9377 /lib/firmware/ath10k/QCA9377/hw1.0/board-2.bin

If this is not helping, would be helpful if you can share the commands and scenario you're running.
Also the dump of the kernel logs.

Ryan
