# NAME

stge — Sundance/Tamarack TC9021 Gigabit Ethernet driver

# SYNOPSIS

stge* at pci? dev ? function ?

Configuration of PHYs or Ten-bit interfaces may also be necessary. See mii(4).

# DESCRIPTION

The stge device driver supports the Sundance/Tamarack TC9021 Gigabit Ethernet chip.

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.

The TC9021 supports IPv4/TCP/UDP checksumming in hardware. The stge driver supports this feature of the chip. See ifconfig(8) for information on how to enable this feature.

# HISTORY

The stge driver first appeared in NetBSD 1.6.

# AUTHORS

The stge driver was written by Jason R. Thorpe <thorpej@NetBSD.org>.

# BUGS

The stge 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.

The stge driver does not yet support jumbo Ethernet frames.

The stge driver does not yet function properly with 1000BASE-T fitted boards. Currently, only 1000BASE-SX boards work.
