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.
