Subject: [PATCH net-next v01 4/4] selftests: net/psock_fanout: socket joins fanout when link is down
Modify test_control_group to have toggle parameter.
When toggle is non-zero, loopback device will be set down for the
initialization of fd[1] which is still expected to successfully join
the fanout.
