This is an API/ABI change notice for DPDK 17.11 on redefinition of port_id. port_id is defined as uint8_t by now, which is just ranged from 0 to 255. For more and more scenerioes, more than 256 devices are needed to support for vdev scalability.
It is necessary for redefinition of port_id to extend from 1 bytes to 2 bytes. All ethdev APIs and use cases related to port_id will be changed at the same time.
