Subjectsungem card fails to find it's mac address
From
Date
Hi all,

I've just been trying out a Sun Gigabit Ethernet card on my PC. As the
sungem module loads it prints out:

Mar 4 20:40:10 monkey kernel: sungem.c:v0.96 11/17/01 David S. Miller
(davem@redhat.com)
Mar 4 20:40:10 monkey kernel: PCI: Enabling device 00:0a.0 (0014 ->
0016)
Mar 4 20:40:10 monkey kernel: PCI: Found IRQ 5 for device 00:0a.0
Mar 4 20:40:10 monkey kernel: PCI: Sharing IRQ 5 with 00:0b.1
Mar 4 20:40:10 monkey kernel: eth0: Sun GEM (PCI) 10/100/1000BaseT
Ethernet 00:00:00:00:00:00

and the card fails to establish a link with the switch (an extreme
networks summit 48). If I then "encourage" the card to have a mac
address (I used one stolen from a 3COM 3c905B!) the link is established
straight away;

(immediately after doing "ifconfig eth0 hw ether 00:10:5A:41:E6:14")

Mar 4 21:06:27 monkey kernel: eth0: Link is up at 1000 Mbps,
full-duplex.
Mar 4 21:06:27 monkey kernel: eth0: PCS AutoNEG complete.
Mar 4 21:06:27 monkey kernel: eth0: PCS link is now up.
Mar 4 21:06:28 monkey kernel: eth0: Link is up at 1000 Mbps,
full-duplex.

After doing this, the card functions as expected, except I get a message
to syslog around once every second saying;

Mar 4 21:18:25 monkey kernel: eth0: Link is up at 1000 Mbps,
full-duplex.

I'm guess this could be the switch forcing a renegotiation every second
and I may be able to turn it off - on the other hand, it could be useful
information for someone;

If any more info is needed please contact me ;)

Also attached is the output of lspci -v
