Why application should explicitly need to load a driver ? Why it cannot happen as part of odp_pktio_open() ? To me a better approach would be: * user reads implementation documentation or uses system commands to find a list of available interfaces * odp_global_init() finds out available pktio interfaces and drivers for those * application opens the interface the user commands (just like today) * pktio_open call loads the driver Or with more ODP support: * odp_global_init() finds out available pktio interfaces and drivers for those * a new API call lists all available interfaces * application chooses an interface from the list and calls open * pktio_open call loads the driver -Petri
