GK blocks typically run at log level NOTICE in production in order to log traffic information. So this patch reduces the priority of two log entries that do not add much in production, are logged often, and are unavoidable. These log entries are as follows: `GATEKEEPER GK: Prefix lookup did not find existing neighbor FIB on back interface, as expected` This log entry and its respective for the front interface come often as routing daemons are always making adjustments to the FIB. Both log entries were at log level NOTICE, and are now INFO.
Gatekeeper servers have to tolerate unwanted traffic at some vantage points. And the following log entry can be excessive and unavoidable: `GATEKEEPER LLS: front interface should not be seeing a packet with EtherType 0x8847` Since LLS blocks typically run at WARNING level in production, this patch changed the log level of this log entry from ERR to NOTICE. As a side note, the EtherType 0x8847 corresonds to MPLS.
