33.Sh NAME
34.Nm gsip
35.Nd National Semiconductor DP83820 Gigabit Ethernet driver
36.Sh SYNOPSIS
37.Cd "gsip* at pci? dev ? function ?"
38.Pp
39Configuration of PHYs may also be necessary.  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.

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. Thorpe
89.Aq thorpej@NetBSD.org .
90.Sh BUGS
91The
92.Nm
93driver does not support the 10-bit interface, which is required in
94order to support fiber-optic media.
