V5X add networking

[davids5]

This adds the config for networking. All tool are enabled for bring up. Telnet is running but we need to tune the config.

Default address is 192.168.0.123 and router is 192.168.0.254

What is the "user facing" story for ethernet, or is it too early to think about this? The sorts of things we might cover are:

1. Any special enabling or config end users need to do. Ie does it just look like a serial port to the rest of the system
2. Whether or not ports are exactly the same as on a computer (just plug in standard cable)
3. Use cases where we recommend it being used

Is there any developer side stuff that needs to be captured too?

@hamishwillee - great questions. There are very many ways to configure the networking. I need to get better requirements to finish the tuning. So yes it too early, but it is good to be thinking about this.
