If by Ethernet, you mean Ethernet 'frames' then that packet is sent to the Controller. The Controller then instructs the Switch about packet modification and actions for output port. Alternatively, the Switch may just send a 'pointer' to the packet rather than sending the whole packet to the Controller.
