Kselftest can be run against older kernels. Instead of failing hard when a feature is unsupported, return the KSFT_SKIP exit code. Specifically, do not fail hard on missing udp zerocopy. The udp gso bench test runs multiple test cases from a single script. Fail if any case fails, else return skip if any test is skipped.

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.
