To make reproducible testing results I would suggest to setup a channel,
(choose one that is the less used by other wireless networks),
problem may happen on some channels and not happen on other.

During this testing period, all clients were simultaneously downloading files from the devices’ sdcard (served via nginx running on the device). Although this is not a typical use-case, it was useful in stress-testing the wireless setup.
For such scenario I would suggest hardcode ba_size = 0 and see if that
would help.
I also attach another patch, can be applied on top of two previous.
This one should give RX hardware more time to provide proper BlockACK
frame, so hopefully could help with seq mismashes.
