See 47.Xr mii 4 . 48.Sh DESCRIPTION 49The 50.Nm 51device driver supports Gigabit Ethernet interfaces based on the 52National Semiconductor DP83820 Gigabit Ethernet chips. 53.Pp 54The National Semiconductor DP83820 is found on NetGear GA-622, 55Asante FriendlyNet GigaNIX, D-Link DGE-500T, SMC 9452TX and 9462TX, and other 56low-cost Gigabit Ethernet cards. It uses an external PHY or an external 5710-bit interface. 58.Pp 59The DP83820 supports VLAN tag insertion/removal in hardware. The 60.Nm 61driver supports this feature of the chip. 62.Pp 63The DP83820 supports IPv4/TCP/UDP checksumming in hardware. The 64.Nm 65driver supports this feature of the chip. See 66.Xr ifconfig 8 67for information on how to enable this feature. 68.Pp 69The DP83820 chip is a close relative of the DP83815 10/100 Ethernet 70chip, which is supported by the 71.Xr sip 4 72driver, hence the 73.Nm 74name. 75.\" .Sh DIAGNOSTICS 76.\" XXX too be done. 77.Sh SEE ALSO 78.Xr arp 4 , 79.Xr ifmedia 4 , 80.Xr mii 4 , 81.Xr netintro 4 , 82.Xr pci 4 , 83.Xr vlan 4 , 84.Xr ifconfig 8 85.Sh HISTORY 86The 87.Nm 88driver first appeared in 89.Nx 1.6 . 90.Sh AUTHORS 91The 92.Nm 93driver was written by 94.An Jason R. Thorpe 95.Aq thorpej@netbsd.org . 96.Sh BUGS 97The 98.Nm 99driver does not support the 10-bit interface, which is required in 100order to support fiber-optic media. 101
