Add a forwarding path test for tc-taprio, based on isochron. This is specifically intended for NICs with an offloaded data path (switchdev/DSA) and requires taprio 'flags 2'. Also, $h1 and $h2 must support hardware timestamping, and $h1 tc-etf offload, for isochron to work. Packets received by a switch while the egress port has a taprio schedule with an open gate for the traffic class must be sent right away. Packets received by the switch while the traffic class gate must be delayed until it opens. Packets received by the switch must be dropped if the gate for the traffic class never opens. Packets should pass if the maximum SDU for the traffic class allows it, and should be dropped otherwise. The schedule should auto-update itself if clock jumps take place while taprio is installed. Repeat most of the above tests after forcing two clock jumps, one backwards (in Jan 1970) and one back into the present. Symlink it from tools/testing/selftests/drivers/net/dsa, because usually DSA ports have the same MAC address, and we need STABLE_MAC_ADDRS=yes from its forwarding.config for the test to run successfully.

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.
