35 .Nd National Semiconductor DP83820 Gigabit Ethernet driver
37 .Cd "gsip* at pci? dev ? function ?"
39 Configuration of PHYs may also be necessary. See
44 device driver supports Gigabit Ethernet interfaces based on the
45 National Semiconductor DP83820 Gigabit Ethernet chips.
47 The National Semiconductor DP83820 is found on NetGear GA-622,
48 Asante FriendlyNet GigaNIX, D-Link DGE-500T, SMC 9452TX and 9462TX,
49 Accton EN1407-T, Planex GN-1000TE, ARK SOHO GA2000T and GA2500T,
50 and other low-cost Gigabit Ethernet
51 cards. It uses an external PHY or an external 10-bit interface.
53 The DP83820 supports VLAN tag insertion/removal in hardware. The
55 driver supports this feature of the chip.
57 The DP83820 supports IPv4/TCP/UDP checksumming in hardware. The
59 driver supports this feature of the chip. See
61 for information on how to enable this feature.
63 The DP83820 chip is a close relative of the DP83815 10/100 Ethernet
64 chip, which is supported by the
82 driver first appeared in
89 .Aq thorpej@NetBSD.org .
93 driver does not support the 10-bit interface, which is required in
94 order to support fiber-optic media.
