net: hns3: refactor queue info of debugfs
Currently, the debugfs command for queue info is implemented by
"echo xxxx > cmd", and record the information in dmesg. It's
unnecessary and heavy. To improve it, create two files
"rx_queue_info" and "tx_queue_info" for it, and query it
by command "cat rx_queue_info" and "cat tx_queue_info",
return the result to userspace, rather than record in dmesg.
The display style is below:
$ cat rx_queue_info
QUEUE_ID BD_NUM BD_LEN TAIL HEAD FBDNUM PKTNUM ...
0 0 0 0 0 0 0 ...
1 0 0 0 0 0 0 ...
2 0 0 0 0 0 0 ...
$ cat tx_queue_info
QUEUE_ID BD_NUM TC TAIL HEAD FBDNUM OFFSET PKTNUM ...
0 0 0 0 0 0 0 0 ...
1 0 0 0 0 0 0 0 ...
2 0 0 0 0 0 0 0 ...
