If I'm not mistaken, it looks like 3c509.c sets the MAC on the
chip from dev->dev_addr in el3_up():
/* Set the station address in window 2 each time opened. */
EL3WINDOW(2);
for (i = 0; i < 6; i++)
outb(dev->dev_addr[i], ioaddr + i);
I don't have the spec for 3c509 handy, but 3c59x.c does the same
thing in vortex_up(), and its spec says the first 6 bytes of register
window 2 are the "StationAddress".
So, I'm still wondering what drivers really never let you change
the MAC address.
