Hao Chen b5a0b70d77 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

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
