Hi, Tetsuya You see lots of places have below three lines:
if (rte_eth_dev_validate_port(port_id) == DEV_INVALID) { PMD_DEBUG_TRACE("Invalid port_id=%d\n", port_id); return -EINVAL; } They are all the same(only few has the print log different), so can we improve it? See below: +static int +rte_eth_dev_validate_port(uint8_t port_id, bool trace) { + if (port_id >= RTE_MAX_ETHPORTS || + rte_eth_devices[port_id].attached != DEV_CONNECTED) { + if (trace) + PMD_DEBUG_TRACE("Invalid port_id=%d\n", port_id); + return DEV_INVALID; + } + else + return DEV_VALID; +} For normal case we just call this function use rte_eth_dev_validate_port(port_id, 1) here 1 could be a enmu value(Thus trace should be defined as int). After call, we didn't need to add PMD_DEBUG_TRACE() any more. For few cases like: PMD_DEBUG_TRACE("set VF rate limit:invalid port id=%d\n", port_id); We can call the function with secondary param set to "0", and add the trace log after the function called, just as before. I think after this enhancement, the code seems more clean and efficiency?
