STGE(4)			 BSD Kernel Interfaces Manual		       STGE(4)

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 Eth‐
     ernet 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 informa‐
     tion on how to enable this feature.

SEE ALSO
     arp(4), ifmedia(4), mii(4), netintro(4), pci(4), ifconfig(8)

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.
