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

What can I do to help debug and fix this?
Regards,
Fredrik
