I'm not great at reading bash but I don't think this tests what we care
about. We want to test bonding's special ability to propagate a netpoll
instances onto its sub-interfaces. So you should be trying to test
different orders of setting and disabling netpoll on the bond and its
sub-interfaces (while the other is setup path is also active).

Since the bonding tests can't run on real HW it can't live directly in
tools/testing/selftests/drivers/net/ we need to move it to either the
netdevsim group or the bonding group.
