Intel AX201 (iwlwifi) flooding syslog with "Got NSS = 4 - trimming to 2"

- OS: Ubuntu 22.04 - Kernel: 5.15.0-135-generic (x86_64) - Machine: Intel NUC11 - Wifi: Intel AX201 (CNVio2) Every couple of seconds I see this message in my syslog:

Mar 31 16:41:12 B2CON00032 kernel: iwlwifi 0000:00:14.3: Got NSS = 4 - trimming to 2

The log spam is interfering with other diagnostics. Why is this there, where is it coming from, and how do I stop it? The wifi is working fine on this machine.
