Vladimir Oltean 469d258d9e Revert "net: stmmac: use sysfs_streq() instead of strncmp()" 
This reverts commit f72cd76b05.
This patch is so broken, it hurts. Apparently no one reviewed it and it
passed the build testing (because the code was compiled out), but it was
obviously never compile-tested, since it produces the following build
error, due to an incomplete conversion where an extra argument was left,
although the function being called was left:

stmmac_main.c: In function ‘stmmac_cmdline_opt’:
stmmac_main.c:7586:28: error: too many arguments to function ‘sysfs_streq’
 7586 |                 } else if (sysfs_streq(opt, "pause:", 6)) {
      |                            ^~~~~~~~~~~

  185 | extern bool sysfs_streq(const char *s1, const char *s2);
      |             ^~~~~~~~~~~

What's even worse is that the patch is flat out wrong. The stmmac_cmdline_opt()
function does not parse sysfs input, but cmdline input such as
"stmmaceth=tc:1,pause:1". The pattern of using strsep() followed by
strncmp() for such strings is not unique to stmmac, it can also be found
mainly in drivers under drivers/video/fbdev/.

With strncmp("tc:", 3), the code matches on the "tc:1" token properly.
With sysfs_streq("tc:"), it doesn't.

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.
