net: hns3: refactor dump fd tcam of debugfs
Currently, the debugfs command for fd tcam is implemented by
"echo xxxx > cmd", and record the information in dmesg. It's
unnecessary and heavy. To improve it, create a single file
"fd_tcam" for it, and query it by command "cat fd_tcam",
return the result to userspace, rather than record in dmesg.
The display style is below:
$ cat fd_tcam
read result tcam key x(31):
00000000
00000000
00000000
08000000
