    So (real world case) I've got a server that's got a 1G ethernet connected to
    the public net, a 1G ethernet that's a cluster management network, and
    a 10G ethernet that connects to our HPC clusters.

    And I want to add iptables rules that distinguish based on interface. Currently
    I can nail the management net to eth0, the public net to eth1, and the 10G to
    eth2, and then just add "-i eth1" or whatever in the iptables ruleset.

    I really don't care if the 0/1/2 move around - but if we're not having nailed-down
    interface names, what will take the place of '-i ethN' in iptables?

    Or is this sort of thing in /etc/udev/rules.d/70-persistent-net.rules
    SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:25:90:0b:f2:80", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
    what you are trying to move to, and my systems are already onboard and
    I should just move along, nothing to see here? ;)
