the ultimate goal is to move all the pci-express hardware support over to e1000e.

since the pci/pci-x generation e1000 chipsets do not have nearly the amount of
features that the pci-e silicon has, you can expect the e1000 driver to be
significantly stripped down.

We do however want to keep any feature that is supported for the pci/pci-x
hardware in e1000 active. we will not disable TSO for instance. As for other
features we will decide whatever makes best sense for the hardware. (e.g. none of
the 8254x chipsets support multiple queues).

All of the primary development of features will focus on e1000e.
