	Hello Ray & All ,  While that RedHat/Debian/... have figured
	these out is really nice .  NOT one of those methods appears to be
	available for hand built distros .  Ie: there does not appear to
	be a standardised(tm) method to approach this difficulty through
	out all drivers (not just ethernet) .

	Could someone please point me to NON RedHat/Debian/... centric
	tool to determine the proper ethernet for now ?

	Modules are not an option for me here .  Imo: If this can be done
	with modules it should well be possible for staticly built
	drivers as well .  Tia , JimL
