+.Sh NAME
+.Nm ixgb
+.Nd "Intel(R) PRO/10GbE Ethernet driver for the FreeBSD operating system"
+.Sh SYNOPSIS
+To compile this driver into the kernel,
+place the following line in your
+kernel configuration file:
+.Bd -ragged -offset indent
+.Cd "device ixgb"
+.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_ixgb_load="YES"
+.Ed
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for PCI Gigabit Ethernet adapters based on
+the Intel 82597EX Ethernet controller chips.
+The driver supports Transmit/Receive checksum offload
+and Jumbo Frames.
+.Pp
+For questions related to hardware requirements,
+refer to the documentation supplied with your Intel PRO/10GbE 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
+.Xr ifconfig 8 .
+.Sh HARDWARE
+The
+.Nm
+driver supports the following cards:
+.Pp
+.Bl -bullet -compact
+.It
+Intel PRO/10GbE LR Server Adapter
+.It
+Intel PRO/10GbE SR Server Adapter
