One additional detail. Even on 4.15 "Unhandled alg" can be reproduced occasionally after disconnecting and reconnecting the adapter to an STA:

дек 22 22:12:45 blade kernel: iwlwifi 0000:3b:00.0: Unhandled alg: 0x707
дек 22 22:12:45 blade kernel: iwlwifi 0000:3b:00.0: Unhandled alg: 0x707
дек 22 22:12:45 blade kernel: iwlwifi 0000:3b:00.0: No association and the time event is over already...

Sometimes there is only one message, sometimes two at the same time and sometimes no message at all.

Seems to be coming from here:

Doesn't affect connectivity though and the card comes up and transmits/receives even after 10 consecutive reconnects.
