NAME
gsip —
National Semiconductor DP83820
Gigabit Ethernet driver
SYNOPSIS
gsip* at pci? dev ? function ?
Configuration of PHYs may also be necessary. See
mii(4).
DESCRIPTION
The
gsip device driver supports Gigabit Ethernet interfaces
based on the National Semiconductor DP83820 Gigabit Ethernet chips.
The National Semiconductor DP83820 is found on NetGear GA-622, Asante
FriendlyNet GigaNIX, D-Link DGE-500T, SMC 9452TX and 9462TX, Accton EN1407-T,
Planex GN-1000TE, ARK SOHO GA2000T and GA2500T, and other low-cost Gigabit
Ethernet cards. It uses an external PHY or an external 10-bit interface.
The DP83820 supports VLAN tag insertion/removal in hardware. The
gsip driver supports this feature of the chip.
The DP83820 supports IPv4/TCP/UDP checksumming in hardware. The
gsip driver supports this feature of the chip. See
ifconfig(8) for information on
how to enable this feature.
The DP83820 chip is a close relative of the DP83815 10/100 Ethernet chip, which
is supported by the
sip(4) driver,
hence the
gsip name.

HISTORY
The
gsip driver first appeared in
NetBSD
1.6.
AUTHORS
The
gsip driver was written by
Jason R.
Thorpe ⟨thorpej@NetBSD.org⟩.
BUGS
The
gsip driver does not support the 10-bit interface, which
is required in order to support fiber-optic media.
