Network problems with nVidia MCP55 network devices

Environment

SUSE Linux Enterprise Server 10 Service Pack 3
SUSE Linux Enterprise Server 10 Service Pack 4

Situation

On hardware with on board nvidia based network cards the network statistic shows many RX Errors or the network doesn't come up after booting. This was reported on devices with Device PCI-ID's 0x0373 and 0x0057 (see below how to check the PCI-ID of your network card).

SuSE Linux Enterprise Server Service Pack 3 ships with an updated forcedeth_new driver that is not affected by the problem. The driver supports only newer models of nVidia network devices, devices with Vendor PCI-ID 0x10DE "nVidia Corporation" and Device PCI-ID's 0x0373 or 0x0057 are not yet supported with the forcedeth_new driver.

You'll find the PCI-ID when you enter 'hwinfo --netcard' on a terminal. In the resulting output look at the line starting with 'Device', it will show pci 0x0373.

Resolution

The kernel maintenance update, kernel version -2.6.16.60-0.66.1 includes patches to resolve the problem on network devices with PCI-ID 0x0373.
The kernel version -2.6.16.60-0.67.1 includes patches to resolve the problem on network devices with PCI-ID 0x0057.

After the update of the kernel including the patches you have to blacklist the forcedeth driver and bind the network device to the forcedeth_new driver. This can be done as follows:
1. Blacklist "forcedeth":
# echo "blacklist forcedeth">> /etc/modprobe.d/blacklist 2. Use YaST to bind the network device's PCI-ID to forcedeth_new: Open YaST -> System -> System Settings -> Add -> Manually
and enter the following fields:
Driver: forcedeth_new Vendor: 10DE Device: 0373
The last step can be automatized so that you don't have to use YaST.
Create the following files and add the content for each file:
# cat /etc/modprobe.d/newid
install forcedeth_new /sbin/modprobe --ignore-install forcedeth_new; echo '10DE
0373' > /sys/bus/pci/drivers/forcedeth_new/new_id

# cat /etc/sysconfig/hardware/hwcfg-vpid-10DE-0373
MODULE='forcedeth_new'
STARTMODE='auto'
MODULE_OPTIONS=''

# cat /etc/sysconfig/hardware/newids 
10DE 0373,forcedeth_new
