- extend the discussion of USB network related config options such that
all available adapter drivers are listed, and that the 'usb' command
for the interactive prompt and scripting becomes available
- suggest to *not* put individual IP configuration parameters into the
exectuable, but instead to put them into external environment or fetch
them from network

You can also set the default IP address of your board and the server

+However note that encoding these individual network settings into a
