Public bug reported:
The onboard Marvell 88E8001 Gigabit Ethernet controler on an ASUS
P4P800-E Deluxe works only at 100MB/s.
I am using Ubuntu Hardy with all the updates installed.
This is happening with linux-generic package versions 2.6.24-16 to 2.6.24-19.
It still happens with linux-backports-modules-hardy installed.
The card with the same switch, cabling, lan etc works normally in
Gigabit mode, when I am booting on windows. The switch is D-link DGS
1005D.
Using ethtool to tune speed has no effect. Disabling auto negotiation
cause the card to fail to connect completely
$ sudo ethtool -s eth0 speed 1000
The lights on the switch show the card as gigabit momentarily and then switch
back to the 100MBps indication. The card works at 100MBps
$ sudo ethtool -s eth0 speed 1000 autoneg off
The card fails to negotiate completely. I can see from the switch that it keeps
trying to connect at gigabit speed (lights on for a second and off for three
four seconds.
