    Here you seem to indicate that delivering power is totally independent
    of the interface admin status, <BROADCAST,MULTICAST>. The interface is
    admin down, yet you can make it deliver power. I thought there might
    be a link between interface admin status and power? Do the standards
    say anything about this? Is there some sort of industrial norm?

    I'm also wondering about the defaults. It seems like the defaults you
    are proposing is power is off by default, and you have to use ethtool
    to enable power. That does not seem like the most friendly
    settings. Why not an 'auto' mode where if the PHY has PoDL PSE
    capabilities, on ifup it is enabled, on ifdown it is disabled? And you
    can put it into a 'manual' mode where you control it independent of
    administrative status of the interface?
