Uhhhh... that is not even remotely recommended. DIsabling arp means, among
other things, that if your network link goes idle for long enough, you
won't be able to talk to your router any more. And if you have any local
machines on the same network, they too will be unreachable when the
existing arp entry times out.

*Batch* arp would be an optimization at the driver level. If it's exposed
in ifconfig at all, it would probably be under mediaopt; but Apple doesn't
include the device specific manpages, at least on 10.9, so no idea how it
shows up. And in any case, ifconfig won't cause your hardware to return a
useful configuration value for it if it's reporting garbage.
