SparcStation 5 with quad 10 mbit ethernet sbus card (qe)

>Description:
	
With -current src from 25.02.2002 the quad 10mbit ethernet sbus card (qe)
in my SparcStation 5 no longer works.

In OBP local-mac-address? is set to false.

The card gets probed at boot time:

qec0 at sbus0 slot 3 offset 0x20000 level 4 (ipl 7): 128K memory
qe0 at qec0 slot 0 offset 0x0 rev 1 address 08:00:20:7a:cc:91
qe1 at qec0 slot 1 offset 0x0 rev 1 address 08:00:20:7a:cc:91
qe2 at qec0 slot 2 offset 0x0 rev 1 address 08:00:20:7a:cc:91
qe3 at qec0 slot 3 offset 0x0 rev 1 address 08:00:20:7a:cc:91

I can configure it up:

qe0: flags=8863<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        address: 08:00:20:7a:cc:91
        media: Ethernet autoselect (10baseT)
        status: active
        inet 10.0.1.59 netmask 0xffffff00 broadcast 10.0.1.255
        inet6 fe80::a00:20ff:fe7a:cc91%qe0 prefixlen 64 scopeid 0x2

but then immediatly I get the following messages:

qe0: rx dma sbus error ack
qe0: resetting...

and the interface is not reachable from outside nor get packets out.

This card used to work under 1.5.3_ALPHA.

Someone else verified the problem on a different sparc with a different
qe card and got the same problem, so I am confident its not a hardware
problem.

>How-To-Repeat:
	
Try to use the quad 10mbit ethernet sbus card (qe) on NetBSD/sparc
with a -current kernel (1.5ZA as from src 25.02.2002).

>Fix:
	
I have no idea :-(
