The temporary solution I use on my MinnowBoard MAX on our custom linux build is, is to issues the following commands in a root shell:
> /etc/init.d/networking stop > ifconfig eth0 hw ether 00:13:20:FE:34:EE > /etc/init.d/networking start > ifconfig eth0 The last command is to confirm the new address one just set, Seems to work great! Hope that helps!

MdePkg/Include/Protocol/SimpleNetwork.h: BOOLEAN MacAddressChangeable; EmbeddedPkg/Drivers/Lan9118Dxe/Lan9118Dxe.c: SnpMode->MacAddressChangeable = TRUE; Nt32Pkg/SnpNt32Dxe/SnpNt32.c: FALSE, // MacAddressChangeable OptionRomPkg/Bus/Usb/UsbNetworking/Ax88772/SimpleNetwork.c: pMode->MacAddressChangeable = TRUE; OptionRomPkg/Bus/Usb/UsbNetworking/Ax88772/SimpleNetwork.c: pMode->MacAddressChangeable = TRUE; OptionRomPkg/Bus/Usb/UsbNetworking/Ax88772b/SimpleNetwork.c: pMode->MacAddressChangeable = TRUE; OptionRomPkg/Bus/Usb/UsbNetworking/Ax88772b/SimpleNetwork.c: pMode->MacAddressChangeable = TRUE; OvmfPkg/VirtioNetDxe/DriverBinding.c: Dev->Snm.MacAddressChangeable = FALSE; I'll write a BSD-licensed UEFI Shell command and offer it to TianoCore, if the interfaces allow it. I've been confused if changing MAC addresses is something you can do in an app or not. I see HP has some LANaddress command, but it appears to not be part of TianoCore.
