Yes wrong, assuming you have access to Linux box with IB stack up and running you could trivially see this if setting ipoib/bonding and then running one of the librdmacm utils while instructing it to bind to a bond (I recommend you go and do that). Now how it works? when the first ipoib device is added to the bond, bonding senses a mismatch between its ethertype to the bond one and calls bond_setup_by_slave(), this along with bonding automatically setting fail_over_mac to be BOND_FOM_ACTIVE for ipoib device, does the job.
