This seems to be related to ANI. I guess you could try start the
ath10k AP and issue:

 echo 0 > /sys/kernel/debug/ieee80211/phy*/ath10k/ani_enable

You can check the current state of the setting by reading the file obviously.

This one is related to software A-MPDU support in ath9k. ath10k
offloads Tx aggregation to firmware so this bug doesn't really apply.
