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?
