In my case:

ath10k: ath10k_peer_assoc_h_crypto: rsn ie found
ath10k: ath10k_peer_assoc_h_crypto: wpa ie found
ath10k: mac peer 00:14:bf:16:b8:44 phymode 11g

Next tx don't work because, FW discard this packets for some reason
(at least broadcast), I see a lot of:
ath10k: htt tx completion msdu_id 0 discard 1 no_ack 0

while with 636 firmware
ath10k: htt tx completion msdu_id 0 discard 0 no_ack 0

So, could be quite different issue you have. I will check switch to
CCMP only while now there is TKIP/CCMP.
