> You can have Ethernet frames carrying IP packets too, but they are not "Ethernet packets"; that would be absurd.

Yes, because "Ethernet packet" would be the wrong way around, layer wise. The pattern is "x y", short for "an y of type x" or "an y containing x" in this case.

It would be "IP frames" by analogy, i.e. Ethernet frames containing IP packets, although I do find that association a bit harder to make.
