Currently, this script sets up the test scenario, which is supposed to end in an inability of the system to negotiate a link. It then waits for a bit, and verifies that the system can diagnose why the link was not established. The wait time for the scenario where different link speeds are forced on the two ends of a loopback cable, was set to 4 seconds, which exactly covered it. As of a recent mlxsw firmware update, this time gets longer, and this test starts failing. The time that selftests currently wait for links to be established is currently $WAIT_TIMEOUT, or 20 seconds. It seems reasonable that if this is the time necessary to establish and bring up a link, it should also be enough to determine that a link cannot be established and why. Therefore in this patch, convert the sleeps to busywaits, so that if a failure is established sooner (as is expected), the test runs quicker. And use $WAIT_TIMEOUT as the time to wait.

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.
