As .config has been removed since the meson build, It is not friendly for new DPDK users to notice those debug options. The patch introduces below build options for data path debug, so PMD can choose to reuse them to avoid maintain their own. - RTE_ETHDEV_DEBUG - RTE_ETHDEV_DEBUG_RX - RTE_ETHDEV_DEBUG_TX The original RTE_LIBRTE_ETHDEV_DEBUG has been replaced by RTE_ETHDEV_DEBUG in the ethdev library as old name is a little bit redundant. Also, all the build options are documented at programming guide "3.1 Driver Option", so users can easily find them.
