a FreeBSD box to do proxy ARP as easily as most commercial routers do, without messing around with (potentially variable) Ethernet addresses. This code is really quite simple; I'm not at all sure why it wasn't implemented in 4.4. It might be worth stealing an interface flag (maybe IFF_LINK1) to use for finer-grained control over which interfaces get proxy treatment. For the moment, it's all or nothing.
