I do not think you need to buy a MAC-Address, you should config the MAC-Address in the Non-Volatile Memory (NVM) of Ethernet Controller 82574IT. Pins on the 82574 are connected to same named pins on the NVM. Please see the Datasheet in detail.
The following is the URL of datasheet of Intel 82574 Gigabit Ethernet Contriller.
