.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
|
|

|
|
.Xr ifconfig 8 .
