1. Yes, this appears to happens every time a unicast packet with 
wpa_supplicant encryption in VHT80 mode is received. I haven't seen a 
successful ping-pong pair.
2. We tried with 10.2.4.70.42-2 firmware and still saw crashes.
3. We ran our experiment again with extra debugging turned on.
     Node A: 18:A6:F7:23:6E:66 | 10.230.5.41
     Node B: 18:A6:F7:26:0F:21 | 10.230.5.42
     The ping command we used was run on Node A was 'ping -s 1500 -i 0.1 
10.230.5.42'
     Here is the dmesg log from Node B.

We noticed in this log that when the radio starts up it says that it is 
in VHT80 mode:
[ 5413.526592] ath10k_pci 0000:01:00.0: mac vdev 0 start center_freq 
5180 phymode 11ac-vht80

But when a peer connects it seems to think the peer is in HT40 mode:
[ 5425.204563] ath10k_pci 0000:01:00.0: mac peer 18:a6:f7:23:6e:66 
phymode 11na-ht40

Compared to no encryption case - this log was taken from Node A:

It seems to start up in VHT80 mode and when it peers with Node B it 
thinks Node B is also in VHT80 mode and ping works.

4. Beacons are sent at 6 Mb/s basic rate and unicast QoS Data is sent 
with three spatial streams. Attached is the full pcap of the experiment.

Thank you for looking into this!
