For some network device models (those where the hardware has an
EEPROM and we're modelling "guest programmed a new MAC address
into the EEPROM") that is the correct behaviour. Is the vmxnet3
definitely one of the kind which is not supposed to have a
permanent MAC address backing storage ? (It's paravirtual, so
this would hopefully be indicated in the specs for it.)
