Disabling "iwlwifi 0000:00:14.3: Unhandled alg: 0x707" from flooding the logs

I was trying to solve this problem too and I think I did it. I turned off some encryption option in iwlwifi and I'm not seeing the constant stream of "Unhandled alg" errors in my log files anymore.

I added this line:

options iwlwifi swcrypto=0

To this file:

/etc/modprobe.d/iwlwifi.conf

and rebooted.

If you need whatever "swcrypto" does, I guess this isn't the best option. But maybe this helps others figure out the problem?
