To get and build dpdk from the root project directory:

git submodule update --init --recursive
make dpdk

To build the project:

export PKG_CONFIG_PATH=<the path of the pkgconfig directory inside dpdk>
make build

To run a very simple test:

In one terminal window

sudo ./build/base-server -l 0 --vdev=net_tap0,iface=tapdpdk

In another terminal window:

sudo ./scripts/testbed-setup.sh
sudo arping -i veth0 1.2.3.4
