I think this change is not correct. Isn't this a radio limitation? I remember something about this when working on the CircuitPython stuff. Need radio integration tests.

Yes this is a limitation of the max packet size of the radio. If I recall correctly the radio module has a 4 byte header and then the Zephyr Radio driver has another 4 byte header leaving us with 248 (256 - 4 -4 = 248) to use for F Prime.
