stge -- Sundance/Tamarack TC9021 Gigabit Ethernet driver
stge* at pci? dev ? function ?
Configuration of PHYs or Ten-bit interfaces may also be necessary. See mii(4).
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.

The stge driver first appeared in NetBSD 1.6.
The stge driver was written by Jason R. Thorpe <thorpej@NetBSD.org>.
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.
