For logging to be useful, something has to set RET and retmsg by calling ret_set_ksft_status(). There is a suite of functions to that end in forwarding/lib: check_err, check_fail et.al. Move them to net/lib.sh so that every net test can use them. Existing lib.sh users might be using these same names for their functions. However lib.sh is always sourced near the top of the file (checked), and whatever new definitions will simply override the ones provided by lib.sh.

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 reStructuredText 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.
