-ETOOMUCHMAGIC. We should either expose all the XX interfaces (but this isn't
a high-speed interface, so let's not) or not "sometimes" convert endianness.
Getting surprises because a field happens to be packed into 4 bytes is
counter-intuitive.

Since your most trivial implementation is to do a byte at a time, I don't
think you have a good argument on that basis either.

Cheers,
Rusty.
