/*
 * The CAN (Controller Area Network) bring-up self-test: the echo run, the
 * comparison of both ends' counters and the error-counter reading.
 *
 * It runs at every start-up, before the bench is usable.  The fault it
 * reports is invisible from every other screen -- a bus that does not carry
 * frames looks exactly like an IOmcu that is not there, and both look
 * like a bench that simply shows no numbers -- so the panel says so itself
 * rather than leaving it to be worked out.
