    This is what I've been using to see whether the spec makes sense.
    A small subset of getters (mostly the unprivileged ones) is implemented.
    Some setters (channels) also work.
    Setters for messages with bitmasks are not implemented.
    
    Initially I was trying to make this tool look 1:1 like real ethtool,
    but eventually gave up :-)
