Application:
Primary: initializes X710 via i40e PMD and iterates in while(1)
Secondary: probes rx_burst successfully with packets until the primary is
killed.
test app:
CMD-1: ./build/basicfwd -w 08:00.2 -l 3
CMD-2: gdb --args ./build/basicfwd -w 08:00.2 -l 4 --proc-type=secondary
traffic generator: ./build/l2fwd -w 83:00.2 --vdev net_tap0,iface=test =l 5
