I'm updating the igb driver to support this feature right now.  I would hesitate to get into other drivers and muck with them because the changes to support this feature are not trivial and also involve policy decisions that I'd prefer to leave up to the folks who maintain those drivers.  Plus I have no other vendor hardware available to test the changes.

I should have the igb driver work done in the next week or so.
