Subject: [PATCH] iwlwifi: don't spam logs with NSS>2 messages
Date: Mon,  5 Sep 2022 19:22:46 +0200	[thread overview]
Message-ID: <20220905172246.105383-1-Jason@zx2c4.com> (raw)

I get a log line like this every 4 seconds when connected to my AP:

[15650.221468] iwlwifi 0000:09:00.0: Got NSS = 4 - trimming to 2

Looking at the code, this seems to be related to a hardware limitation,
and there's nothing to be done. In an effort to keep my dmesg
manageable, downgrade this error to "debug" rather than "info".
