Hi, thanks for that correction. Do you have a keyword or 2 to google for "They can be modified, though not necessarily in a typical way." Or is that only or the CM, and not the normal RPI4?

I only found some quick&dirty patch, that seems to make MTU up to 2000 functional. But since the patch aims for 9018, and only gets 2000, that does not seem like the "right" solution.
