Remove Stat Messages

Originally from ticket #6607.

How do we remove the following messages from being logged?

0> 85:17:30:01.530 [2] [STAT] BER=0.00E+00, RSSI=-46, MSE=-35, SYS_TEMP=30
1> 85:17:30:01.530 [2] [STAT] RF PORT: IN(0 Mbps, util=0) OUT(0 Mbps,
util=0)
2> 85:17:30:16.660 [2] [STAT] BER=0.00E+00, RSSI=-46, MSE=-35, SYS_TEMP=30
3> 85:17:30:16.660 [2] [STAT] RF PORT: IN(0 Mbps, util=0) OUT(0 Mbps,
util=0)
4> 85:17:30:31.740 [2] [STAT] BER=0.00E+00, RSSI=-46, MSE=-35, SYS_TEMP=30

Change the loglevel to 0 1 <loglevel 0 1> and then save the config.

It is also possible to filter the display in newer firmware releases by using syslog 1. However, it is still typically best to change the log level so that the syslog can hold information for longer durations.
