Add a test case that can support different types of faulty links for all
protocol versions (HSRv0, HSRv1, PRPv1). It starts with a baseline with
fully functional links. The first faulty case is one link being cut during
the ping. This test uses a different function for ping that sends more
packets in shorter intervals to stress the duplicate detection algorithms a
bit more and allow for future tests with other link faults (packet loss,
reordering, etc.).
As the link fault tests now cover the cut link for HSR and PRP, it can be
removed from the hsr_ping test. Note that the removed cut link test did not
really test the fault because do_ping_long takes about 1sec while the link
is only cut after a 3sec sleep.

We get a significant number of conflicts between net and net-next
because of selftests Makefile changes. People tend to append new
test cases at the end of the Makefile when there's no clear sort
order. Sort all networking selftests Makefiles, use the following
format:
VAR_NAME := \
entry1 \
entry2 \
entry3 \
# end of VAR_NAME
Some Makefiles are already pretty close to this.

works correctly.

Some of the code already present in the hsr_ping.sh test program can be
moved to a separate script file, so it can be reused by other HSR
functionality (like HSR-SAN) tests.

This test adds a basic HSRv0 network with 3 nodes. In its current shape
it sends and forwards packets, announcements and so merges nodes based
on MAC A/B information.
It is able to detect duplicate packets and packetloss should any occur.
