Network problems with nVidia MCP55 network devices
This document (7006203) is provided subject to the disclaimer at the end of this document.
SUSE Linux Enterprise Server 10 Service Pack 4
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.

The kernel version -18.104.22.168-0.67.1 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":The last step can be automatized so that you don't have to use YaST.
# 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
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
