The Mac generates the Ethernet frame preamble and the CRC. You still need to provide a full Ethernet header, including the source and destination MAC addresses.

The MAC address that you set with those two registers is mostly used for the receiving part. The Mac includes a filter that will only let you receive the Ethernet packets that are sent to the configured MAC address, or the broadcast packets. The other packets are ignored and not transmitted to the avalon stream.
