I've merged this for now (with a slightly different commit message):

    [networking] add ethtool -d
    
    Add 'ethtool -d <dev>' to the networking plugin. This retrieves
    and prints a register dump for the specified network device.
    
    This may be required to debug some low-level network interface
    problems (e.g. embedded card configuration values) that would
    otherwise require the use of proprietary diagnostic tools.

I spoke to a couple of network driver engineers and the feeling was that
this should be reasonably safe; we'll keep an eye out for problems with
the command before the next release.
