[src/trunk]: src Introduce rump.arp
details: https://anonhg.NetBSD.org/src/rev/de4155b3a9f6
branches: trunk
changeset: 339574:de4155b3a9f6
user: ozaki-r <ozaki-r%NetBSD.org@localhost>

description:
Introduce rump.arp
arp(8) uses RTM that requires that getpid(2) works correctly. Unfortunately
supporting getpid(2) in librumphijack will be tricky so that we rump-ify
arp(8) as well as ifconfig and route commands.
Suggested by pooka@.
