Sorry, I don't think I will have time to work on this issue in the coming weeks. If you plan to do it, I will be happy to help with reviews and comments. As I said in a previous message, I think a good first step would be to introduce a typedef for the port number: rte_eth_port_num_t. It can still be uint8_t for now, and can be switched to 16 bits in one step when everyone uses this new type. Olivier
