>Description:
	Only the first interface works (i.e. can send/receive packets).

	at device autoconfig time:

	qec0 at sbus0 slot 0 offset 0x20000 level 4 (ipl 7): 128K memory
	qe0 at qec0 slot 0 offset 0x0 rev 1 address 08:00:20:19:c2:65
	qe1 at qec0 slot 1 offset 0x0 rev 1 address 08:00:20:19:c2:65
	qe2 at qec0 slot 2 offset 0x0 rev 1 address 08:00:20:19:c2:65
	qe3 at qec0 slot 3 offset 0x0 rev 1 address 08:00:20:19:c2:65

	at ifconfig time, the kernel spews:

	NMI: system interrupts: 40000000<VME=0,SBUS=0,ME>
	qe0: eint: qestat=8000000<CLOSS>
	qe0: no carrier, link down?
	qe1: eint: qestat=8000000<CLOSS>
	qe1: no carrier, link down?

	This despite all four interfaces being connected to hubs,
	with link showing on for all.

	While in operation, the kernel frequently logs:

Apr  4 15:59:36 ipswitch /netbsd: qe0: rint: no packets; rb index 102; status 0x80000800
Apr  4 16:48:37 ipswitch /netbsd: qe0: rint: no packets; rb index 142; status 0x80000800
Apr  4 16:50:02 ipswitch /netbsd: qe0: rint: no packets; rb index 183; status 0x80000800
Apr  4 16:50:03 ipswitch /netbsd: qe0: rint: no packets; rb index 197; status 0x80000800
Apr  4 16:50:03 ipswitch /netbsd: qe0: rint: no packets; rb index 211; status 0x80000800

	N.B. - this system is using a stripped down kernel with
	just SUN4M MMU support, and GATEWAY defined with no IPSEC
	(so that the ipflow fast routing code is enabled).

>How-To-Repeat:
	Install a qec into a SPARC LX with NetBSD 1.5.3_RC1 installed,
	and attempt to use it. Note Failure of all interfaces other than zero.
