National Semiconductor PCI 10/100/1Gb Ethernet device

## NAME

**nge** – National Semiconductor PCI 10/100/1Gb Ethernet device

## SYNOPSIS

**nge\* at pci?** **nsgphy\* at mii?**

## DESCRIPTION

The **nge** driver provides support for various NICs based on the National Semiconductor DP83820 and DP83821 Gigabit Ethernet controller chips, including the following:

- Addtron AEG320T

- Ark PC SOHO-GA2500T (32-bit PCI) and SOHO-GA2000T (64-bit PCI)

- Asante FriendlyNet GigaNIX 1000TA and 1000TPC

- D-Link DGE-500T

- Linksys EG1032v1 (32-bit PCI) and EG1064v1 (64-bit PCI)

- Netgear GA621

- Netgear GA622T

- SMC EZ Card 1000 (SMC9462TX)

- Surecom Technology EP-320G-TX

- TRENDnet TEG-PCITX (32-bit PCI) and TEG-PCITX2 (64-bit PCI)

The **nge** driver supports IPv4 receive IP/TCP/UDP checksum offload, VLAN tag insertion and stripping, as well as a 2048-bit multicast hash filter and up to 4 pattern match buffers.

The **nge** driver also supports jumbo frames.

The **nge** driver supports the following media types:

- **autoselect**

  Enable autoselection of the media type and options. The user can manually override the autoselected mode by adding media options to the appropriate [hostname.if(5)](/hostname.if/5.md) file.

- **10baseT**

  Set 10Mbps operation. The [ifconfig(8)](/ifconfig/8.md) **mediaopt** option can also be used to select either **full-duplex** or **half-duplex** modes.

- **100baseTX**

  Set 100Mbps (Fast Ethernet) operation. The [ifconfig(8)](/ifconfig/8.md) **mediaopt** option can also be used to select either **full-duplex** or **half-duplex** modes.

- **1000baseT**

  Set 1000baseT operation over twisted pair. Both **full-duplex** and **half-duplex** modes are supported.

- **1000baseSX**

  Set 1000Mbps (Gigabit Ethernet) operation. Both **full-duplex** and **half-duplex** modes are supported.

The **nge** driver supports the following media options:

- **full-duplex**

  Force full duplex operation.

- **half-duplex**

  Force half duplex operation.
