I think it's made clear in the tomás quotation, about 18 lines above
Richard's citation of the same. Regardless, the OP is connecting two
machines (requiring firmware) running DEs on stretch, and has an
8-port switch lying around too, so not much chance of needing to
chop up cables (unless in frustration at having to use them at all).
No progress reported yet, though, AFAICT.
