The "min_rx_bufsize" is the minimum buffer hardware supported in Rx. Actually, network engines also have the maximum buffer. So this series introduce maximum Rx buffer size in struct rte_eth_dev_info and display it by testpmd. --- v1: - move max_rx_bufsize to min_rx_bufsize closer in struct rte_eth_dev_info - add max_rx_bufsize display in testpmd. - hns3 reports maximum buffer size.
