OK, I also have an identical card sitting in a Sun Enterprise 450 box.
In case someone can tell me how to do it in Solaris 8 I can check how 
the card is configured there.

BTW, please CC me as I'm not subscribed to the list.

No, doing the test from solaris/Sparc isn't going to work.

You're trying this on an x86 system right?  If so that's the crux of
the problem, you need to dump the PCI resources from Linux for some
x86 wizard to look at.

the most verbose I've found is "prtconf -v". I remember a long time ago,
someone showed me something which strangely looked like lspci with an
hex dump, but I don't remember what, unfortunately.

I hope this helps a bit.

sungem 0.97 driver doesn't work with "Sun GigabitEthernet/P 2.0" card.

[Fredrik Ohrn]

Hello!

I have salvaged a Sun GigabitEthernet/P 2.0 card from a retired Sun server 
and am trying to put it to use.


Inserting the driver gives the following in dmesg:

sungem.c:v0.97 3/20/02 David S. Miller (davem@redhat.com)
eth2: Sun GEM (PCI) 10/100/1000BaseT Ethernet 00:00:00:00:00:00
gem: SW reset is ghetto.

Notice the missing MAC address.


Configuring the card gives the following:

[root@olivia ~]# ifconfig eth2 129.xxx.xxx.17 netmask 255.255.255.128 broadcast 129.xxx.xxx.127
[root@olivia ~]# ifconfig eth2
eth2      Link encap:Ethernet  HWaddr 00:00:00:00:00:00  
          inet addr:129.xxx.xxx.17  Bcast:129.xxx.xxx.127  Mask:255.255.255.128
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:4294967170
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:4294967254
          collisions:4294967212 txqueuelen:100 
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)
          Interrupt:22 Base address:0x7000 

Notice the bogus frame, carrier and collision error counts.


When trying to communicate with the box using 129.xxx.xxx.17 it will 
advertize the MAC address of eth0 on ARP queries. This means that to other 
machines 129.xxx.xxx.17 seems to work just fine but in reality the 
traffic passes over eth0, not the sungem card. Similar things seems to 
happen when trying to do outward connections.


Gritty system details:

Plain 2.4.19 kernel.
ASUS TR-DLS mobo with ServerWorks LE chipset.
The card is 64-bit and sits in a 64-bit PCI slot.

[root@olivia ~]# lspci -v -x -s 01:02

30: 01 00 00 40 00 00 00 00 00 00 00 00 09 01 40 40



What can I do to help debug and fix this?


Regards,
Fredrik

   gem: SW reset is ghetto.

If you get this message you won't get a working card at all.

Most likely the BIOS isn't assigning resources to the card
correctly.  Some x86 guru would need to look at PCI config
space dumps to figure out what might be going wrong.
