+.Sh NAME
+.Nm igb
+.Nd "Intel(R) PRO/1000 PCI Express Gigabit Ethernet adapter driver"
+.Sh SYNOPSIS
+To compile this driver into the kernel,
+place the following line in your
+kernel configuration file:
+.Bd -ragged -offset indent
+.Cd "device igb"
+.Ed
+.Pp
+Alternatively, to load the driver as a
+module at boot time, place the following line in
+.Xr loader.conf 5 :
+.Bd -literal -offset indent
+if_igb_load="YES"
+.Ed
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for PCI Express Gigabit Ethernet adapters
+based on the Intel 82575 and 82576 Ethernet controller chips.
+The driver supports Transmit/Receive checksum offload and Jumbo
+Frames.
+Furthermore it supports TCP segmentation offload (TSO) on all
+adapters.
+.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 9216.
+.Pp
+This driver supports hardware assisted VLANs.
+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 .
