However, only register values are exported, which is inconvenient for users to interpret. Therefore, an extension of the structure "rte_dev_reg_info" and a new API rte_eth_dev_get_reg_info_ext is added to support the capability of exporting the name of the corresponding register and filtering by names. The hns3 driver and telemetry are examples for that. -- v5: 1. fix version map. 2. fix comment on rte_eth_dev_get_reg_info_ext. 3. set RTE_ETH_REG_NAME_SIZE to 64. 4. fix default register name. 5. add support for reg_info->width == 8 in telemetry. 6. add memeory allocate fail log. 7. fix memory access for telemetry to store extra registers. v4: 1. fix mispellings. 2. add const to 'filter'. 3. remove redundant assigning. v3: 1. fix mispellings. 2. use snprintf instead of sprintf. 3. add more comment on rte_eth_dev_get_reg_info_ext. 4. add __rte_experimental. 5. add version map. v2: 1. fix compile error. 2. add new API to support it instead of the old one. 3. split patches on hns3 driver.
