The tests in net/forwarding are generally expected to be HW-independent. There are however several tests that, while not depending on any HW in particular, nevertheless depend on being used on HW interfaces. Placing these selftests to net/forwarding is confusing, because the selftest will just report it can't be run on veth pairs. At the same time, placing them to a particular driver's selftests subdirectory would be wrong. Instead, add a new directory, drivers/net/hw, where these generic but HW independent selftests should be placed. Move over several such tests including one helper library. Since typically these tests will not be expected to run, omit the directory drivers/net/hw from the TARGETS list in selftests/Makefile. Retain a Makefile in the new directory itself, so that a user can make -C into that directory and act on those tests explicitly.
