.Sh NAME
.Nm em
.Nd "Intel(R) PRO/1000 Gigabit Ethernet adapter driver"
.Sh SYNOPSIS
.Cd "device em"
.Sh DESCRIPTION
The
.Nm
driver provides support for PCI Gigabit Ethernet adapters based on
the Intel 82540, 82541ER, 82541PI, 82542, 82543, 82544, 82545, 82546,
82546EB, 82546GB, 82547 and 82573 Ethernet controller chips.
The driver supports Transmit/Receive checksum offload
and Jumbo Frames only on 82540, 82543, 82544 and 82546-based adapters.
For further hardware information, see the
.Pa README
included with the driver.
.Pp
For questions related to hardware requirements,
refer to the documentation supplied with your Intel PRO/1000 adapter.
All hardware requirements listed apply to use with
.Fx .
.Pp
Support for Jumbo Frames is provided 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.
The maximum MTU size for Jumbo Frames is 16114.
.Pp
This driver version supports VLANs.
For information on enabling VLANs, see the
.Pa README .
The
.Nm
driver supports the following media types:
.Bl -tag -width ".Cm 10baseT/UTP"
.It Cm autoselect
Enables auto-negotiation for speed and duplex.
.It Cm 10baseT/UTP
Sets 10Mbps operation.
Use the
.Cm mediaopt
option to select
.Cm full-duplex
mode.
.It Cm 100baseTX
Sets 100Mbps operation.
Use the
.Cm mediaopt
option to select
.Cm full-duplex
mode.
.It Cm 1000baseSX
Sets 1000Mbps operation.
Only
.Cm full-duplex
mode is supported at this speed.
.It Cm 1000baseTX
Sets 1000Mbps operation.
Only
.Cm full-duplex
mode is supported at this speed.
.El
.Pp
The
.Nm
driver supports the following media options:
.Bl -tag -width ".Cm full-duplex"
.It Cm full-duplex
Forces full-duplex operation
.It Cm half-duplex
Forces half-duplex operation.
.El
.Pp
Only use
.Cm mediaopt
to set the driver to
.Cm full-duplex .
If
.Cm mediaopt
is not specified, the driver defaults to
.Cm half-duplex .
.Pp
For more information on configuring this device, see
.Xr ifconfig 8 .
.Sh HARDWARE
The
.Nm
driver supports Gigabit Ethernet adapters based on the Intel
82540, 82541ER, 82541PI, 82542, 82543, 82544, 82545, 82546, 82546EB,
