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". Cc: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Jason A.
