No it doesn't work that way. The Avalon memory mapped interface is only used to configure the registers in the mac.

You will need to set up a few registers to enable and configure the Mac. For that you supply the address and data on address and write_data, put a '1' on the write signal, and wait for waitrequest to go back to '0'. Then you can write another value.

To send a packet, you need to use the Avalon stream sink ff_tx. You don't have any address there, just send your words one after the others and use the rdy/wren for flow control.

Those interfaces are described in the Avalon spec.
