NAME
nge - National Semiconductor PCI gigabit ethernet adapter driver
SYNOPSIS
device miibus
device nge
DESCRIPTION
The nge driver provides support for various NICs based on the National
Semiconductor DP83820 and DP83821 gigabit ethernet controller chips,
including the following:
o SMC EZ Card 1000 (SMC9462TX)
o D-Link DGE-500T
o Asante FriendlyNet GigaNIX 1000TA and 1000TPC
o Addtron AEG320T
o LinkSys EG1032 (32-bit PCI) and EG1064 (64-bit PCI)
o Surecom Technology EP-320G-TX
o Netgear GA622T
o Netgear GA621
o Ark PC SOHO-GA2500T (32-bit PCI) and SOHO-GA2000T (64-bit PCI)
o Trendware TEG-PCITX (32-bit PCI) and TEG-PCITX2 (64-bit PCI)
All of these NICs are capable of 10, 100 and 1000mbps speeds over CAT5
copper cable. The DP83820 supports TBI (ten bit interface) and GMII
transceivers, which means it can be used with either copper or 1000baseX
fiber applications. The DP83820 supports TCP/IP checksum offload and
VLAN tagging/insertion as well as a 2048-bit multicast hash filter and up
to 4 pattern match buffers.
Most cards also use the DP83861 10/100/1000 copper gigabit transceiver
chip, which supports autonegotiation of 10, 100 and 1000mbps modes in
full or half duplex.
The DP83820 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.
