Extending DEVLINK_ATTR_PERM_CFG (permanent/NVRAM device configuration) to include NPAR settings: DEVLINK_ATTR_PERM_CFG_NPAR_NUM_PARTITIONS_PER_PORT: Number of NIC Partitions (NPAR) per port. DEVLINK_ATTR_PERM_CFG_NPAR_BW_IN_PERCENT: 1 if BW_RESERVATION and BW_LIMIT is in percent; /0 if BW_RESERVATION and BW_LIMIT is in 100 Mbps units. DEVLINK_ATTR_PERM_CFG_NPAR_BW_RESERVATION: Configures NPAR bandwidth or weight reservation, in percent or 100 Mbps units, depending on BW_IN_PERCENT. DEVLINK_ATTR_PERM_CFG_NPAR_BW_RESERVATION_VALID: 1 to use BW_RESERVATION setting, 0 to ignore. DEVLINK_ATTR_PERM_CFG_NPAR_BW_LIMIT: Configures NPAR bandwidth or weight limit, in percent or 100 Mbps units, depending on BW_IN_PERCENT. DEVLINK_ATTR_PERM_CFG_NPAR_BW_LIMIT_VALID: 1 to use BW_LIMIT setting, 0 to ignore.
