The DPDK site seems to imply that they include complete replacement drivers. My assumption was that those drivers, while perhaps providing additional APIs, also supported the APIs that the standard drivers provide. Is that wrong?

Looks like Intel thought so too. See https://01.org/packet-processing/intel%C2%AE-ovdk - that job seems to be done already, and they're well on their way to a smart switch.

There is likely some facility for this, since they claim linear scalability across cores.
