12.2.1.2. Insert Source Address
If you configure the IP core to use source address insertion, the MAC replaces the bytes in the Source Addr field provided by the client interface with the source address given by the txmac_saddr register.
To enable source address insertion, turn on Use Source Address Insertion in the GTS Ethernet Hard IP parameter editor.
