Overview

The re driver provides support for various NICs based on the Realtek RTL8139C+, RTL8169, RTL816xS, RTL811xS, RTL8168 and RTL810xE PCI and PCI Express Ethernet controllers, including the following:

• Alloy Computer Products EtherGOLD 1439E 10/100 (8139C+)

• Buffalo LGY-PCI-GT (8169S)

• Compaq Evo N1015v Integrated Ethernet (8139C+)

• Corega CG-LAPCIGT (8169S)

• D-Link DGE-528T (8169S)

• D-Link DGE-530T C1 (8169/8110SB)

• D-Link DGE-660TD (8169/8110SB)

• Gigabyte 7N400 Pro2 Integrated Gigabit Ethernet (8110S)

• LevelOne GNC-0105T (8169S)

• Linksys EG1032v3 (8169S)

• Netgear GA311 (8169S)

• Netgear GA511 PC Card (8169)

• PLANEX COMMUNICATIONS Inc. GN-1200TC (8169S)

• Surecom EP-320G-TX1 (8169S)

• TTTech MC322 (8139C+)

• US Robotics USR997902 (8169S)

• Xterasys XN-152 10/100/1000 NIC (8169)

NICs based on the 8139C+ and 810xE are capable of 10 and 100Mbps speeds over CAT5 cable. NICs based on the 8169, 816xS, 811xS and 8168 are capable of 10, 100 and 1000Mbps operation.

All re NICs support IPv4 transmit/receive IP/TCP/UDP checksum offload, VLAN tag insertion and stripping, and use a descriptor-based DMA mechanism. The 8102E(L), 8103E(L), 8168C/8111C, 8168D/8111D, 8168DP/8111DP and 8168E/8111E chips also support IPv6 receive TCP/UDP checksum offload.

The 8139C+ is a single-chip solution combining both a 10/100 MAC and PHY. The 8169 is a 10/100/1000 MAC only, requiring a GMII or TBI external PHY. The 8169S, 8110S, 8111B and 8168 are single-chip devices containing both a 10/100/1000 MAC and 10/100/1000 copper PHY. Standalone 10/100/1000 cards are available in both 32-bit PCI and 64-bit PCI models. The 8110S and 8111B are designed for embedded LAN-on-motherboard applications.

The 8168, 8169, 8169S and 8110S also support jumbo frames.

The re driver additionally supports Wake on LAN (WoL). See arp(8) and ifconfig(8) for more details.

The re driver supports the following media types:

autoselect

Enable autoselection of the media type and options. The user can manually override the autoselected mode by adding media options to the appropriate hostname.if(5) file.

10baseT/UTP

Set 10Mbps operation. The ifconfig(8) mediaopt option can also be used to select either full-duplex or half-duplex modes.

100baseTX

Set 100Mbps (Fast Ethernet) operation. The ifconfig(8) mediaopt option can also be used to select either full-duplex or half-duplex modes.

1000baseT

Set 1000baseT operation over twisted pair. The Realtek GigE chips support 1000Mbps in full-duplex mode only.

The re driver supports the following media options:

full-duplex

Force full duplex operation.

half-duplex

Force half duplex operation.

For more information on configuring this device, see ifconfig(8).
