The TSE uses two Avalon Stream interfaces for Ethernet packets: a source with received packets and a sink for packets to transmit. Usually in a design with a Nios II CPU and a software layer with a TCP/IP stack, those two interfaces are connected to SGDMAs in QSys. If you do it that way and have the correct software solution, then you can directly send and receive packets through the software API.

If you need a higher bandwidth you can also make your own IP and connect it to the avalon stream interfaces in QSys instead of the DMAs and generate packets directly there.
