IXGB(4)			  OpenBSD Programmer's Manual		       IXGB(4)

NAME
     ixgb - Intel PRO/10GbE 10Gb Ethernet device

SYNOPSIS
     ixgb* at pci?

DESCRIPTION
     The ixgb driver provides support for PCI-X 10Gb Ethernet adapters based
     on the Intel 82597EX Ethernet controller chips.  The driver supports IPv4
     receive IP/TCP/UDP checksum offload, VLAN tag insertion and stripping,
     and Jumbo frames.	This includes the following models:

	   Intel PRO/10GbE CX4 Server Adapter (PXLA8591CX4)
	   Intel PRO/10GbE LR Server Adapter (PXLA8591LR)
	   Intel PRO/10GbE SR Server Adapter (PXLA8591SR)
	   Sun 10 Gigabit Ethernet PCI-X Adapter (X5544A-4)

     The ixgb driver supports the following media types:

	   autoselect  Enables auto-negotiation for speed and duplex.

	   10GbaseLR   Sets 10Gbps operation.  Only full-duplex mode is
		       supported at this speed.

	   10GbaseSR   Sets 10Gbps operation.  Only full-duplex mode is
		       supported at this speed.

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

     ifconfig(8)

HISTORY
     The ixgb device driver first appeared in OpenBSD 3.9.

AUTHORS
     The ixgb driver was written by Intel Corporation.

BUGS
     Under small packet UDP stress tests with 10GbE driver, the OpenBSD system
     will drop UDP packets due to the fullness of the socket buffers.  You may
     want to change the driver's Flow Control variables to the minimum value
     for controlling packet reception.

     Excessive CRC errors may be observed if the Intel PRO/10GbE CX4 Server
     adapter is connected to a Fujitsu XENPAK CX4 module in a SmartBits
     chassis using 15m/24AWG cable assemblies manufactured by Fujitsu or
     Leoni.  The CRC errors may be received either by the Intel PRO/10GbE CX4
     Server adapter or the SmartBits.  If this situation occurs, using a
     different cable assembly may resolve the issue.

     Excessive CRC errors may be observed if the Intel PRO/10GbE CX4 Server
     adapter is connected to an HP Procurve 3400cl switch port using short
     cables (1m or shorter).  If this situation occurs, using a longer cable
     may resolve the issue.

     Excessive CRC errors may be observed using Fujitsu 24AWG cable assemblies
     that are 10m or longer or where using a Leoni 15 m/24AWG cable assembly.
     The CRC errors may be received either by the CX4 Server adapter or at the
     switch.  If this situation occurs, using a different cable assembly may
     resolve the issue.
