Are saying there are requirements around for systems to have networking
up and running with the first second after RTEMS starting ? I am
impressed you can boot, start the BSP timer running, files system up and
working (flash?), initialised the network stack and have a valid link
all within one 1 second.

How long does a recent GigE PHY take to negotiate a link with a switch ?
