I can confirm that the unmodified driver with a patched firmware fixes 
the issue on QCA9377 as well. I appended the mfp-support flag to the 
existing flags for both firmware variants that are relevant to my device:

./ath10k-fwencoder --modify --features=ignore-otp-result,mfp-support 
firmware-5.bin
./ath10k-fwencoder --modify 
--features=wowlan,ignore-otp-result,mfp-support firmware-6.bin

Testing each firmware individually confirms the flag is now present, and 
both firmware versions can now reach 300Mbps.

ath10k_pci 0000:02:00.0: firmware ver WLAN.TF.1.0-00002-QCATFSWPZ-5 api 
5 features ignore-otp,mfpcrc32 18db2397
ath10k_pci 0000:02:00.0: firmware ver WLAN.TF.2.1-00021-QCARMSWP-1 api 6 
features wowlan,ignore-otp,mfpcrc32 02bceae2

I would be happy to submit the modified firmware, but I am skeptical 
that it would be accepted? I'm not sure if I've ever observed 
unofficial/modified wifi firmware to ever have been accepted into 
linux-firmware (which seems completely understandable, given the risks).
