Then adding a non\nARPHRD_ETHER member forced the bonding master to change its type.\n\nThe fix is to make sure we call dev_close() in bond_setup_by_slave()\nso that the potential linked lapbether devices (or any other devices\nhaving assumptions on the physical device) are removed.\n\nA similar bug has been addressed in commit 40baec225765\n(\"bonding: fix panic on non-ARPHRD_ETHER enslave
