FAUCET controlling OVS + DPDK

https://github.com/REANNZ/faucet/blob/master/docs/vendors/ovs/README_OVS-DPDK.rst

DPDK enables high performance packet processing on PC type platforms with certain supported NICs. In particular OVS has DPDK support, and can offload work to DPDK NICs.

While this is beyond the scope of what FAUCET does (it works at the OpenFlow level), getting up and running quickly with OVS + DPDK is useful. Hopefully as DPDK packaging continues to include the process will become less complex.
