selftests: hsr: Reorder the testsuite.
Move the code and group into functions so it will be easier to extend the test to HSRv1 so that both versions are covered. Move the ping/test part into do_complete_ping_test() and the interface setup into setup_hsr_interfaces(). Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: David S.
