tulip on alpha ds10l 100MbpsFD problem

[Vladimir Lazarenko <vlad@lazarenko.net>]

Hello,

I'm trying to get this DS 10L going with Linux, and I hit the ceiling  
with the onboard ethernet.
Whenever the device is in 10Mbps, and switch is in 10 Mbps,  
everything works ok (half-duplex mode). Whenever I switch to 100Mbps,  
I'm not able to receive packets. At all. Sending goes ok, i.e. I see  
DHCP requests on another server, but nothing reaches the box when  
data is sent to it.

Similar behaviour with both de4x5 and tulip drivers.

Note, that it thinks that the device is in 10mbps full duplex mode,  
however when i force 10mbps on the switch, it will report 10mbps half- 
duplex, and that's the only configuration it works properly in.

SRM ewa0_mode is set to FastFD. It doesn't work with Auto-Negotiate  
either.

Any ideas would be very welcome. I'd be very happy to get this baby  
going in 100Mbps mode.
As a sidenote, alphaserver800 which is next to it, works in 100MbpsFD  
perfectly.

Regards,
Vladimir
