See 40.Xr mii 4 . 41.Sh DESCRIPTION 42The 43.Nm 44device driver supports Gigabit Ethernet interfaces based on the 45National Semiconductor DP83820 Gigabit Ethernet chips. 46.Pp 47The National Semiconductor DP83820 is found on NetGear GA-622, 48Asante FriendlyNet GigaNIX, D-Link DGE-500T, SMC 9452TX and 9462TX, 49Accton EN1407-T, Planex GN-1000TE, ARK SOHO GA2000T and GA2500T, 50and other low-cost Gigabit Ethernet 51cards. It uses an external PHY or an external 10-bit interface. 52.Pp 53The DP83820 supports VLAN tag insertion/removal in hardware. The 54.Nm 55driver supports this feature of the chip. 56.Pp 57The DP83820 supports IPv4/TCP/UDP checksumming in hardware. The 58.Nm 59driver supports this feature of the chip. See 60.Xr ifconfig 8 61for information on how to enable this feature. 62.Pp 63The DP83820 chip is a close relative of the DP83815 10/100 Ethernet 64chip, which is supported by the 65.Xr sip 4 66driver, hence the 67.Nm 68name. 69.\" .Sh DIAGNOSTICS 70.\" XXX too be done. 71.Sh SEE ALSO 72.Xr arp 4 , 73.Xr ifmedia 4 , 74.Xr mii 4 , 75.Xr netintro 4 , 76.Xr pci 4 , 77.Xr vlan 4 , 78.Xr ifconfig 8 79.Sh HISTORY 80The 81.Nm 82driver first appeared in 83.Nx 1.6 . 84.Sh AUTHORS 85The 86.Nm 87driver was written by 88.An Jason R.
