Replying to my own question, is it a function: 1) of the UEFI network
driver returning TRUE or FALSE in the Simple Network Protocols's
MacAddressChangable, and 2) there being an end-user command available or
one that can be built with TianoCore-exposed interfaces?

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.

Thanks again.
