Hi, Stephen, Thanks for your review. The app proc-info and ethtool already support dump registers with the rte_eth_dev_get_reg_info API. For the use of the new API, I think it's better to discuss whether to add or replace the API of the two apps after the API of the new version is applied. Best Regards, Jie Hai
