.Sh NAME
.Nm re
.Nd "RealTek 8139C+/8169/8169S/8110S PCI Ethernet adapter driver"
.Sh SYNOPSIS
.Cd "device miibus"
.Cd "device re"
.Sh DESCRIPTION
The
.Nm
driver provides support for various NICs based on the RealTek RTL8139C+,
RTL8169, RTL8169S and RTL8110S PCI Ethernet controllers.
.Pp
NICs based on the 8139C+ are capable of 10 and 100Mbps speeds over CAT5
cable.
NICs based on the 8169, 8169S and 8110S are capable of 10, 100 and
1000Mbps operation.
.Pp
All NICs supported by the
.Nm
driver have TCP/IP checksum offload and hardware VLAN tagging/insertion
features, and use a descriptor-based DMA mechanism.
They are also
capable of TCP large send (TCP segmentation offload).
.Pp
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 and 8110S 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 is designed for
embedded LAN-on-motherboard applications.
.Pp
The 8169, 8169S and 8110S also support jumbo frames, which can be configured
via the interface MTU setting.
Selecting an MTU larger than 1500 bytes with the
.Xr ifconfig 8
utility configures the adapter to receive and transmit jumbo frames.
.Pp
The
.Nm
driver supports the following media types:
.Bl -tag -width ".Cm 10baseT/UTP"
.It Cm autoselect
Enable autoselection of the media type and options.
The user can manually override
the autoselected mode by adding media options to
.Xr rc.conf 5 .<commit_msg>document the limit on jumbo frame size..<commit_after>.\" Copyright (c) 2003

The 8169, 8169S and 8110S also support jumbo frames, which can be configured

The MTU is limited to 7422, since the chip cannot transmit larger frames.

utility configures the adapter to receive and transmit jumbo frames.
