When exporting and running a subset of selftests via kselftest, files from
parts of the source tree which were not exported are not available. A few
tests are trying to source such files. Address the problem by using
symlinks.
The problem can be reproduced by running:
make -C tools/testing/selftests gen_tar TARGETS="drivers/net/bonding"
[... extract archive ...]
./run_kselftest.sh
or:
make kselftest KBUILD_OUTPUT=/tmp/kselftests TARGETS="drivers/net/bonding"
Fixes: bbb774d921 ("net: Add tests for bonding and team address list management")
Fixes: eccd0a80dc ("selftests: net: dsa: add a stress test for unlocked FDB operations")

This has been validated on the Ocelot/Felix switch family (NXP LS1028A)
and should be relevant to any switch driver that offloads the tc-flower
and/or tc-matchall actions trap, drop, accept, mirred, for which DSA has
operations.

Add a Makefile which takes care of installing the selftests in
tools/testing/selftests/drivers/net/dsa. This can be used to install all
DSA specific selftests and forwarding.config using the same approach as
for the selftests in tools/testing/selftests/net/forwarding.

This adds an initial subset of forwarding selftests which I considered
to be relevant for DSA drivers, along with a forwarding.config that
makes it easier to run them (disables veth pair creation, makes sure MAC
addresses are unique and stable).
The intention is to request driver writers to run these selftests during
review and make sure that the tests pass, or at least that the problems
are known.

This test is a bit strange in that it is perhaps more manual than
others: it does not transmit a clear OK/FAIL verdict, because user space
does not have synchronous feedback from the kernel. If a hardware access
fails, it is in deferred context.
Nonetheless, on sja1105 I have used it successfully to find and solve a
concurrency issue, so it can be used as a starting point for other
driver maintainers too.
