All:

I have improved upon my original OpenBSD carp(4) logging patch by
merging the FreeBSD patch into NetBSD 4.

Patch:
http://people.collaborativefusion.com/~seklecki/nbsd4-ip_carp.c-logging.patch

Screenshot:

I have file NetBSD pr#: kern/38260

There are still some issues with the CARP_LOG macro -- thus some message
get a duplicate interface name prefix. The C99 style macro in FreeBSD
doesn't port cleanly.
