It's not, typically, read from the ROM every time it's needed. It's read *ONCE* during startup, into a buffer in the driver, and that be overwritten by later code. And the tools to do THAT are commonly supplied with the OS, because you might be replacing a former NIC (or entire machine) in a context where the old MAC address is known and perhaps embedded in various other devices. Easier to mimic the old node than to hunt down every reference....
