Running this test makes little sense if the enabled l3_stats are not actually reported as "used". This can signify a failure of a driver to install the necessary counters, or simply lack of support for enabling in-HW counters on a given netdevice. It is generally impossible to tell from the outside which it is. But more likely than not, if somebody is running this on veth pairs, they do not intend to actually test that a certain piece of HW can install in-HW counters for the veth. It is more likely they are e.g. running the test by mistake. Therefore detect that the counter has not been actually installed. In that case, if the netdevice is one end of a veth pair, SKIP. Otherwise FAIL.

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.
