See 40.Xr mii 4 . 41.Sh DESCRIPTION 42The 43.Nm 44device driver supports the Sundance/Tamarack TC9021 Gigabit Ethernet 45chip. 46.Pp 47The Sundance/Tamarack TC9021 is found on the D-Link DGE-550T, and 48the Antares Microsystems Gigabit Ethernet board. It uses an external 49PHY or an external 10-bit interface. 50.Pp 51The TC9021 supports IPv4/TCP/UDP checksumming in hardware. The 52.Nm 53driver supports this feature of the chip. See 54.Xr ifconfig 8 55for information on how to enable this feature. 56.\" .Sh DIAGNOSTICS 57.\" XXX too be done. 58.Sh SEE ALSO 59.Xr arp 4 , 60.Xr ifmedia 4 , 61.Xr mii 4 , 62.Xr netintro 4 , 63.Xr pci 4 , 64.Xr ifconfig 8 65.Sh HISTORY 66The 67.Nm 68driver first appeared in 69.Nx 1.6 . 70.Sh AUTHORS 71The 72.Nm 73driver was written by 74.An Jason R. Thorpe 75.Aq thorpej@NetBSD.org . 76.Sh BUGS 77The 78.Nm 79driver does not support the VLAN tag insertion/removal feature of the 80TC9021 chip. This is primarily because the TC9021's VLAN do not have 81a useful programming interface. 82.Pp 83The 84.Nm 85driver does not yet support jumbo Ethernet frames. 86.Pp 87The 88.Nm 89driver does not yet function properly with 1000BASE-T fitted boards. 90Currently, only 1000BASE-SX boards work. 91
