    description: "The netmap-pkt-gen-multinode can be used to measure the performance of a simple l2fwd
                  application in a multinode setup. A typical setup is two machines connected back to
                  back through a pair of interfaces (usually intel server DPDK dual NICs like the 82599
                  dual port 10GB interface) where the l2fwd runs on one machine and netmap runs on the
                  other. The test launches a pkt-gen instance to send packets on one interface and another
                  one to receive packets and count them on the other interface."
