I found a reference to "local-mac-address" in OF_getetheraddr2 in=20
ofw_machdep.c
   return (OF_getprop(node, "local-mac-address", addr, ETHER_ADDR_LEN))

but I can't see how setting local-mac-address to true makes sense here.

OF_getetheraddr reads a OF property of "idprom". In theory there must=20
be a similar property for the QFE card. But I am not the OF guru to dig=20=

into that further.
