When two host is connected directly without any devices like switch,
and also enable dedicated tx/rx queues on bonding devices slaves,
rx_machine_update would recieving partner lacp negotiation packets,
which partner's port mac filled with zeros. So in this situation,
it would never go rx_machine branch with correct mac!
Thus bond mode 4 will negotiation failed.
