RE: [10GBASE-T] Auto-Negotiation Support

But, what if is not just a stand alone NIC? I can see embedded applications
that would require operation in low power modes. Why limit the applications?
Is there a significant cost associated with the trade off of supporting
auto-negotiation at 100/1000/10000 Mbps vs. 1000/10000 Mbps. If so, can
someone clarify the cost implications?

Microsoft has the only WOL support requirement I know of.  It is an optional
feature in PCI/PCI Power Management Specs.  Microsoft's requirement is that
the Desktop/Server support WOL on a least one NIC.  That can be accomplished
by most all of the Fast (10/100) or Gigabit (10/100/1000T) embedded or
standup NICs today and possibly 1000SX in the near future.  We're
considering the 10GBase-T to be a high speed, stand-alone option NIC.  In
which case, it doesn't require WOL.

Is the study group considering the PCI and PCI-E power management
requirements for an add-in adapter implementation of 10GBASE-T? To my
knowledge the low power management requirement can only be met by the
current 1000Base-T controllers when running at 10/100 Mpbs. Hence, I can see
the need for supporting auto-negotiation that includes 100Base-T and
1000Base-T. The controller should be able to negotiate down to 100 Mbps when
operating in a lower power mode i.e. Wake on LAN or remote management(ASF,
