tools: allow binding to other network class devices

dpdk_nic_bind will only handle Ethernet devices, but Mellanox ConnectX-3 Pro,
for example, is a Network class device, but not an Ethernet one. Even though
this allows other devices in the list, like Wireless devices, this should not be
a problem.
