The main conclusion so far is that this write (net/dsa/mv88e6131.c):

	/*
	 * MAC Forcing register: don't force link, speed, duplex
	 * or flow control state to any particular values.
	 */
	REG_WRITE(addr, 0x01, 0x0003);

isn't correct on ports that can either be CPU ports or external ports.
Forcing the link up on the CPU port helps somewhat, but things aren't
100% working yet.
