add support for NAT under netperf stream, maerts, and spec-surge.

configs/boot/spec-surge-client.rcS:
configs/boot/surge-client.rcS:
    fix this rcS - don't sleep, instead wait for the server to tell you it's done.
configs/boot/spec-surge-server.rcS:
configs/boot/surge-server.rcS:
    notify the client you're done starting the server.
