Should do it in bellows if using newer emberznet. Per Silabs, they still validate the data frame, so if we received it, then the FCS is assumed to be correct.

Sure. It should be possible to directly overwrite the 802.15.4 FCS within bellows itself then, without pulling in the scapy dependency. I think it's computed over the entire packet?
