net: hns3: refactor dump qos buf cfg of debugfs
Currently, user gets qos buffer config by implementing debugfs command "echo dump qos buf cfg > cmd", this command will dump info in dmesg. It's unnecessary and heavy. To optimize it, create a single file "qos_buf_cfg" in tm directory and use cat command to get info. It will return info to userspace, rather than record in dmesg. The display style is below: $ cat qos_buf_cfg tx_packet_buf_tc_0: 0x120 tx_packet_buf_tc_1: 0x120 tx_packet_buf_tc_2: 0x120 tx_packet_buf_tc_3: 0x120 tx_packet_buf_tc_4: 0x0 tx_packet_buf_tc_5: 0x0 tx_packet_buf_tc_6: 0x0 tx_packet_buf_tc_7: 0x0 ......
