See 47.Xr mii 4 . 48.Sh DESCRIPTION 49The 50.Nm 51device driver supports the Sundance/Tamarack TC9021 Gigabit Ethernet 52chip. 53.Pp 54The Sundance/Tamarack TC9021 is found on the D-Link DGE-550T, and 55the Antares Microsystems Gigabit Ethernet board. It uses an external 56PHY or an external 10-bit interface. 57.Pp 58The TC9021 supports IPv4/TCP/UDP checksumming in hardware. The 59.Nm 60driver supports this feature of the chip. See 61.Xr ifconfig 8 62for information on how to enable this feature. 63.\" .Sh DIAGNOSTICS 64.\" XXX too be done. 65.Sh SEE ALSO 66.Xr arp 4 , 67.Xr ifmedia 4 , 68.Xr mii 4 , 69.Xr netintro 4 , 70.Xr pci 4 , 71.Xr ifconfig 8 72.Sh HISTORY 73The 74.Nm 75driver first appeared in 76.Nx 1.6 . 77.Sh AUTHORS 78The 79.Nm 80driver was written by 81.An Jason R. Thorpe 82.Aq thorpej@netbsd.org . 83.Sh BUGS 84The 85.Nm 86driver does not support the VLAN tag insertion/removal feature of the 87TC9021 chip. This is primarily because the TC9021's VLAN do not have 88a useful programming interface. 89.Pp 90The 91.Nm 92driver does not yet support jumbo Ethernet frames. 93.Pp 94The 95.Nm 96driver does not yet function properly with 1000BASE-T fitted boards. 97Currently, only 1000BASE-SX boards work. 98
