    I found it to be the easiest way to implement things. It allowed
    me to not have to touch any of layer 3, and I did not have to patch
    any user-space program like ip or ifconfig.

    I'm not even sure if the nay-sayers ever had another idea, they
    just didn't like having lots of interfaces. Originally, there
    were claims of inefficiency, but it seems that other than things
    like 'ip' and ifconfig, there are no serious performance problems
    I am aware of.

    Adding the hashed lookup for devices took the exponential curve out of
    ip and ifconfig's performance, btw.
