.Dd June 2, 2001 .Dt GSIP 4 .Os .Sh NAME .Nm gsip .Nd National Semiconductor DP83820 Gigabit Ethernet driver .Sh SYNOPSIS .Cd "gsip* at pci? dev ? function ?"
p Configuration of PHYs may also be necessary. See .Xr mii 4 . .Sh DESCRIPTION The .Nm device driver supports Gigabit Ethernet interfaces based on the National Semiconductor DP83820 Gigabit Ethernet chips.
p 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.
p The DP83820 supports VLAN tag insertion/removal in hardware. The .Nm driver supports this feature of the chip.
p The DP83820 supports IPv4/TCP/UDP checksumming in hardware. The .Nm driver supports this feature of the chip. See .Xr ifconfig 8 for information on how to enable this feature.
p
The DP83820 chip is a close relative of the DP83815 10/100 Ethernet
chip, which is supported by the
.Xr sip 4
driver, hence the
.Nm
name.
.Sh DIAGNOSTICS
XXX too be done.

.Sh HISTORY
The
.Nm
driver first appeared in
.Nx 1.6 .
.Sh AUTHORS
The
.Nm
driver was written by
.An Jason R. Thorpe
.Aq thorpej (at] NetBSD.org .
.Sh BUGS
The
.Nm
driver does not support the 10-bit interface, which is required in
order to support fiber-optic media.
