nfe: NVIDIA nForce MCP Ethernet driver


nfe - NVIDIA nForce MCP Ethernet driver


To compile this driver into the kernel, place the following lines in your kernel configuration file: device miibus device nfe Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5): if_nfe_load="YES"


The nfe driver supports PCI Ethernet adapters based on the NVIDIA nForce Media and Communications Processors (MCP), such as the nForce, nForce 2, nForce 3, CK804, MCP04, MCP51, MCP55, MCP61, MCP65, MCP67, MCP73, MCP77 and MCP79 Ethernet controller chips. Supported features include (hardware support provided): +
The nfe driver supports the following NVIDIA MCP onboard adapters: +
Tunables can be set at the loader(8) prompt before booting the kernel or stored in loader.conf(5). hw.nfe.msi_disable Whether or not MSI support is enabled in the driver. The default value is 0. hw.nfe.msix_disable Whether or not MSI-X support is enabled in the driver. The default value is 0.


The following sysctl(8) variables can be used to modify or monitor nfe behavior. dev.nfe.%d.process_limit Maximum number of Rx events to be processed in the event loop before rescheduling a taskqueue. The accepted range is 50 to 255, the default value is 192. The interface does not need to be brought down and up again before a change takes effect.

The nfe device driver first appeared in OpenBSD 3.9, and then in FreeBSD 7.0.


The nfe driver was written by Jonathan Gray <jsg@openbsd.org> and Damien Bergamini <damien@openbsd.org>. The nfe driver was ported to FreeBSD by Shigeaki Tagashira <shigeaki@se.hiroshima-u.ac.jp>. NFE(4)
