The threat of forks is overstated.  No single vendor is going to throw the
resources needed to properly maintain the full dpdk release just so they can get
their one driver into the same tree.

Also, I'm not sure if this helps, but the approach being taken in the napatech
tree is fairly heavyweight.  Instead of cloning the entire dpdk tree, they could
just be maintaining the drivers/net/napatech directory, with build instructions
indicating that a user should clone and build dpdk, then build their tree, after
setting RTE_SDK/RTE_SRCDIR/etc appropriately.
