.Dd March 16, 2011 .Dt VXGE 4 .Os .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: d -ragged -offset indent .Cd "device vxge" .Ed
p Alternatively, to load the driver as a module at boot time, place the following line in .Xr loader.conf 5 : d -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.
p The .Nm driver supports the following function modes: d -ragged -offset indent .Cd "SF1_VP17 - 1 function with 17 VPATHs" .Ed d -ragged -offset indent .Cd "MF8_VP2 - 8 functions with 2 VPATHs per function" .Ed d -ragged -offset indent .Cd "MF2_VP8 - 2 functions, 8 Paths/Function" .Ed d -ragged -offset indent .Cd "MF4_VP4 - 4 Functions, 4 Paths/Function" .Ed d -ragged -offset indent .Cd "MF8P_VP2 - 8 functions with 2 VPATHs per function required for DirectIO" .Ed
p For general information and support, please visit the Neterion support page
a http://www.neterion.com/support/support.html .
p 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.
p 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
a http://www.neterion.com where additional information and a kernel patch can be found.
p 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
a http://www.neterion.com . .Sh SUPPORT For troubleshooting tips and FAQs, please visit
