# NAME

`gsip` —
National Semiconductor DP83820 Gigabit Ethernet driver

# SYNOPSIS

`gsip* at pci? dev ? function ?`

Configuration of PHYs may also be necessary. See mii(4).

# DESCRIPTION

The `gsip` device driver supports Gigabit Ethernet interfaces based on the National Semiconductor DP83820 Gigabit Ethernet chips.

The National Semiconductor DP83820 is found on NetGear GA-622, Asante FriendlyNet GigaNIX, D-Link DGE-500T, SMC 9452TX and 9462TX, Accton EN1407-T, Planex GN-1000TE, ARK SOHO GA2000T and GA2500T, and other low-cost Gigabit Ethernet cards. It uses an external PHY or an external 10-bit interface.

The DP83820 supports VLAN tag insertion/removal in hardware. The `gsip` driver supports this feature of the chip.

The DP83820 supports IPv4/TCP/UDP checksumming in hardware. The `gsip` driver supports this feature of the chip. See ifconfig(8) for information on how to enable this feature.

The DP83820 chip is a close relative of the DP83815 10/100 Ethernet chip, which is supported by the sip(4) driver, hence the `gsip` name.

# HISTORY

The `gsip` driver first appeared in NetBSD 1.6.

# AUTHORS

The `gsip` driver was written by Jason R. Thorpe ⟨thorpej@NetBSD.org⟩.

# BUGS

The `gsip` driver does not support the 10-bit interface, which is required in order to support fiber-optic media.
