net: hns3: refactor dump bd info of debugfs
Currently, the debugfs command for bd info is implemented
by "echo xxxx > cmd", and record the information in dmesg.
It's unnecessary and heavy.
To improve it, add two debugfs directories "tx_bd_info" and
"rx_bd_info", and create a file for each queue under these
two directories, and query the bd info of specific queue by
"cat tx_bd_info/tx_bd_queue*" or "cat rx_bd_info/rx_bd_queue*",
return the result to userspace, rather than record in dmesg.
The display style is below:
$ cat rx_bd_info/rx_bd_queue0
Queue 0 rx bd info:
BD_IDX L234_INFO PKT_LEN SIZE...
0 0x0 60 60...
1 0x0 1512 1512...
$ cat tx_bd_info/tx_bd_queue0
Queue 0 tx bd info:
BD_IDX ADDRESS VLAN_TAG SIZE...
0 0x0 0 0...
1 0x0 0 0...
