carp_input: packet received on non-carp interface log flooding
Where a non-CARP system is on the same broadcast domain as a CARP system, the system logs get flooded once a second with messages like:
carp_input: packet received on non-carp interface: sis1
Rendering the system log unusable. This is new to FreeBSD 8.0-based versions. Need to get rid of this log noise.
