Then why there are again byte swaps with big endian target, aren't
they bogus too? Because we don't have the byte swapping bus yet.
Current system is bogus in this respect, so I claim that in general,
the level of bogosity was not changed.

I agree that the user visible property solution was wrong, sorry.

I had a patch "Compile rtl8139 and e1000 only once", which had "be"
property too but I didn't commit it because the property passing
didn't feel right and I didn't have a plan how to pass that from
higher levels.

Other patches didn't use the property method.
