.Dd July 24, 2001 .Dt STGE 4 .Os .Sh NAME .Nm stge .Nd Sundance/Tamarack TC9021 Gigabit Ethernet driver .Sh SYNOPSIS .Cd "stge* at pci?" .Cd "eephy* at mii?"
p Configuration of PHYs or Ten-bit interfaces may also be necessary. See .Xr mii 4 . .Sh DESCRIPTION The .Nm device driver supports the Sundance/Tamarack TC9021 Gigabit Ethernet chip.
p
The Sundance/Tamarack TC9021 is found on the D-Link DGE-550T, and
the Antares Microsystems Gigabit Ethernet board.
It uses an external PHY or an external 10-bit interface.
.Pp
The TC9021 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.
.Sh DIAGNOSTICS
XXX too be done.

.Sh HISTORY
The
.Nm
driver first appeared in
.Ox 3.1 .
.Sh AUTHORS
The
.Nm
driver was written by
.An Jason R. Thorpe Aq thorpej@netbsd.org .
.Sh BUGS
The
.Nm
driver does not support the VLAN tag insertion/removal feature of the
TC9021 chip.
This is primarily because the TC9021's VLAN do not have a useful
programming interface.
p The .Nm driver does not yet support jumbo Ethernet frames.
