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) file.

10baseT

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

100baseTX

Set 100Mbps (Fast Ethernet) operation. The ifconfig(8) 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.
