Apart from this, if the test was not started because the max lanes of the designated device is 0. The script will still return 0 and thus causing a false-negative test result.

They also test for the recent syzbot bug[1] which causes a warning and results in wrong device flags (IFF_SLAVE missing). The test adds three bond devices and a nlmon device, enslaves one of the bond devices to the other and then uses the nlmon device for successful and unsuccesful enslaves both of which change the bond ether type. Thus we can test for both MASTER and SLAVE flags at the same time.
