I have added new documentation for our working configuration of DPDK. We will document our configurations and insights as we work with the Split 7.2 testbed.

Thanks to @aayamrajshakya for improving our documentation for the new features, and making our website more clear. We are now working on more accurate and comprehensive diagrams to include in the docs, as well as adding sections for the configuration of each component.
