—
National Semiconductor PCI
10/100/Gigabit 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,
which can be configured via the interface MTU setting. Selecting an MTU
larger than 1500 bytes with the
ifconfig(8) utility configures the adapter to receive and transmit
Jumbo frames. Using Jumbo frames can greatly improve performance for certain
tasks, such as file transfers and data streaming.
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 eitherfull-duplex
orhalf-duplex
modes. 100baseTX
- Set 100Mbps (Fast Ethernet) operation. The
ifconfig(8)
mediaopt
option can also be used to select eitherfull-duplex
orhalf-duplex
modes. 1000baseT
- Set 1000baseT operation over twisted pair. Both
full-duplex
andhalf-duplex
modes are supported. 1000baseSX
- Set 1000Mbps (Gigabit Ethernet) operation. Both
full-duplex
andhalf-duplex
modes are supported.
The nge
driver supports the following
media options:
full-duplex
- Force full duplex operation.
half-duplex
- Force half duplex operation.
For more information on configuring this device, see ifconfig(8).
