IPv4 proxy_arp is different.  It's the way of configuring automatic
proxy ARP.  No such thing exists for IPv6 at the moment, so when we
implement ND proxying, it would probably be the place to toggle it on
and off.  So I see little need for a sysctl toggle to switch this on
and off, as the addresses to be proxied are currently manually
configured anyway.

I'm not sure whether this is called for, for a small piece of code
like this.  We need fewer configuration options, not more! :-)
