I still like the idea of having --per-protocol. Here's some more thoughts.
`dhcpcd --per-protocol eth0` should probably be equivalent to `dhcpcd
--per-protocol -4 eth0; dhcpcd --per-protocol -6 eth0`, which suggests
we could have `dhcpcd --per-protocol -x eth0`, killing both instances.
In that case `dhcpcd -x eth0` should probably do nothing and error.
Equivalently, this means when we started dhcpcd using simply `dhcpcd
eth0`, that attempting `dhcpcd --per-protocol -x eth0` should do
nothing and error.
