VXGE(4) 						   BSD Kernel Interfaces Manual 						   VXGE(4)

NAME

     vxge -- Neterion X3100 10GbE Server/Storage adapter driver

SYNOPSIS

     To compile this driver into the kernel, place the following line in your kernel configuration file:

	   device vxge

     Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

	   if_vxge_load="YES"

DESCRIPTION

     The vxge 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.

     The vxge driver supports the following function modes:

	   SF1_VP17 - 1 function with 17 VPATHs

	   MF8_VP2 - 8 functions with 2 VPATHs per function

	   MF2_VP8 - 2 functions, 8 Paths/Function

	   MF4_VP4 - 4 Functions, 4 Paths/Function

	   MF8P_VP2 - 8 functions with 2 VPATHs per function required for DirectIO

     For general information and support, please visit the Neterion support page http://www.neterion.com/support/support.html.

     Support for Jumbo Frames is provided via the interface MTU setting.  Selecting an MTU larger than 1500 bytes with the ifconfig(8) utility
     configures the adapter to transmit and receive Jumbo Frames.  X3100 adapters support Jumbo Frames up to 9600 bytes.

     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 http://www.neterion.com where additional information and a kernel patch can be found.

     For more information on configuring this device, see ifconfig(8).

HARDWARE

     The vxge driver supports Neterion X3100 10 Gigabit Ethernet adapters listed in http://www.neterion.com.

CXGB(4) 						   BSD Kernel Interfaces Manual 						   CXGB(4)

NAME

     cxgb -- Chelsio T3 10 Gigabit Ethernet adapter driver

SYNOPSIS

     To compile this driver into the kernel, place the following lines in your kernel configuration file:

	   device firmware
	   device cxgb

     To load the driver as a module at boot time, place the following line in loader.conf(5):

	   if_cxgb_load="YES"

DESCRIPTION

     The cxgb driver supports Transmit/Receive checksum offload, Jumbo Frames, TCP segmentation offload (TSO), Large Receive Offload (LRO), VLAN
     hardware insertion / extraction, and VLAN checksum offload.  For further hardware information, see http://www.chelsio.com/.

     For questions related to hardware requirements, refer to the documentation supplied with your Chelsio T3 adapter.	All hardware requirements
     listed apply to use with FreeBSD.

     Support for Jumbo Frames is provided via the interface MTU setting.  Selecting an MTU larger than 1500 bytes with the ifconfig(8) utility
     configures the adapter to receive and transmit Jumbo Frames.  The maximum MTU size for Jumbo Frames is 9000.

     For more information on configuring this device, see ifconfig(8).

HARDWARE

     The cxgb driver supports 10 Gigabit and 1 Gigabit Ethernet adapters based on the T3 and T3B chipset:

     o	 Chelsio 10GBase-CX4
     o	 Chelsio 10GBase-LR
     o	 Chelsio 10GBase-SR

LOADER TUNABLES

     Tunables can be set at the loader(8) prompt before booting the kernel or stored in loader.conf(5).

DIAGNOSTICS

     cxgb%d: Unable to allocate bus resource: memory  A fatal initialization error has occurred.

     cxgb%d: Unable to allocate bus resource: interrupt  A fatal initialization error has occurred.

     cxgb%d: Could not find firmware image %s  The appropriate firmware kld module was not installed.  This is a fatal initialization error.

SUPPORT

     For general information and support, go to the Chelsio support website at: http://www.chelsio.com/.

     If an issue is identified with the released source code on the supported kernel with a supported adapter, email the specific information
     related to the issue to <support@chelsio.com>.
