See PR conf/23063 with the "[PATCH] for static ARP tables in
rc.network" synopsis. It allows you to do everything statically
or just "seed" your table on bootup and still have the kernel
learn new entries.
There's been a short thread in the -security list around the time
of the PR's submission discussing that this is not a very clean
and reliable method of preventing attacks but mostly gives "warm
fuzzies" for those of us who like static configuration. :)
