+.Sh NAME
+.Nm vxge
+.Nd "Neterion X3100 10GbE Server/Storage 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 vxge"
+.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_vxge_load="YES"
+.Ed
+.Sh DESCRIPTION
+The
+.Nm
+driver provides support for Neterion X3100 adapters.
+The driver supports TCP Segmentation Offload (TSO/LSO),
+Large Receive Offload (LRO), Jumbo Frames, Receive Traffic Hash (RTH),
+VLAN, Promiscuous mode and Multi function mode.
+.Pp
+The
+.Nm
+driver supports the following function modes:
+.Bd -ragged -offset indent
+.Cd "SF1_VP17 - 1 function with 17 VPATHs"
+.Ed
+.Bd -ragged -offset indent
+.Cd "MF8_VP2 - 8 functions with 2 VPATHs per function"
+.Ed
+.Bd -ragged -offset indent
+.Cd "MF2_VP8 - 2 functions, 8 Paths/Function"
+.Ed
+.Bd -ragged -offset indent
+.Cd "MF4_VP4 - 4 Functions, 4 Paths/Function"
+.Ed
+.Bd -ragged -offset indent
+.Cd "MF8P_VP2 - 8 functions with 2 VPATHs per function required for DirectIO"
+.Ed
+.Pp
+For general information and support, please visit the Neterion support page
+.Pa http://www.neterion.com/support/support.html .
+.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 transmit and receive Jumbo Frames.
+X3100 adapters support Jumbo Frames up to 9600 bytes.
+.Pp
+For Jumbo Frames, the driver will try to allocate physically contiguous buffers.
+Failures to do so may degrade the performance.
+To resolve such problems, please visit
+.Pa http://www.neterion.com
+where additional information and a kernel patch can be found.
+.Pp
+For more information on configuring this device, see
+.Xr ifconfig 8 .
+.Sh HARDWARE
+The
+.Nm
+driver supports Neterion X3100 10 Gigabit Ethernet adapters listed in
