I don't have much in the way of review comments, it all looks pretty
good to me, for whatever that's worth.  I am excited for this support to
be mainlined, it will be super useful for our routers and provides and
extensible way I can eventually add support for additional PSE chipsets,
like the LTC4266 from Linear Technology.

I look forward to working with this to add support for port priorities
and power management given a system-level power budget that is less than
the sum of total power that could be supplied by all ports.  I don't
know exactly how this will look, but I do know that without this first
part, it wouldn't be possible.

So, great work, and thanks for the effort.  It's appreciated and will be
very useful for us.  I look forward to working with you to build on top
of this.

Thanks so much,
Kyle
