Existing MC driver framework is based on MC-9.x.x flib. This patch migrates MC obj (DPBP, DPNI, DPRC, DPMAC etc) to use latest MC flib which is MC-10.3.0. Changes introduced due to migration: 1. To get OBJ token, pair of create and open API replaces create APIs 2. Pair of close and destroy APIs replaces destroy APIs 3. For version read, get_version APIs replaces get_attributes APIs 4. dpni_get/reset_statistics APIs replaces dpni_get/set_counter APIs 5. Simplifies struct dpni_cfg and removes dpni_extended_cfg struct 6. Single API dpni_get_buffer_layout/set_buffer_layout replaces dpni_get_rx/set_rx, tx related, tx_conf_buffer_layout related APIs. New API takes a queue type as an argument. 7. Similarly dpni_get_queue/set_queue replaces dpni_get_rx_flow/set_rx_flow , tx_flow related, tx_conf related APIs Signed-off-by: Yogesh Gaur <yogeshnarayan.gaur@nxp.com> Signed-off-by: Priyanka Jain <priyanka.jain@nxp.com> Reviewed-by: York Sun <york.sun@nxp.com>
