As I've mentioned in my other mail - perhaps reordering is disabled in
firmware under some circumstances.

My suspicion is monitor vdev may be involved. It is created in
firmware when you set ath10k interface into promisc mode (bridging
implies that; most sniffers set promisc mode too unless told to not
to, e.g. tcpdump -p).

Can you somehow verify if you observe the reordering problem without
bridging with ethernet (e.g. run traffic to AP w/ bridging and w/o
bridging) ? If it's too much work then forget it :-)
