for gigabit don't use crossover cable - the cards should autoneg crossover, and crossover cable has to be different than the normal 100 cross to work for giga...

Hi all,
I have two HP DL145 G1 machines, running centos4 (2.6.9-22.0.2.ELsmp). Nics are recognized as:
eth0: Tigon3 [partno(BCM95704) rev 2002 PHY(5704)] (PCIX:100MHz:64-bit) 10/100/1000BaseT Ethernet 00:00:1a:19:f1:05 eth0: RXcsums[1] LinkChgREG[0] MIirq[0] ASF[0] Split[0] WireSpeed[1] TSOcap [1] eth1: Tigon3 [partno(BCM95704) rev 2002 PHY(5704)] (PCIX:100MHz:64-bit) 10/100/1000BaseT Ethernet 00:00:1a:19:f1:04 eth1: RXcsums[1] LinkChgREG[0] MIirq[0] ASF[0] Split[0] WireSpeed[1] TSOcap [1]
Both machines are wired in the same way: eth0 is connected do 100mbit switch, eth1 to a gigabit switch. But:
# mii-tool eth0: negotiated 100baseTx-FD, link ok eth1: negotiated 100baseTx-FD flow-control, link ok
If I force eth1 to 1000 with ethtool, I get no link and then it autonegotiates itself back to 100. I can't even get them to talk at gigabit speed if I connect both machines together with crossover cable!
Am I doing something wrong or is this a hardware problem?
