     In addition to Intel's own ``PRO/1000'' line of Gigabit Ethernet interfaces, these chips also appear on some server systems, processor evalu-
     ation boards, and in embedded systems.

     The i8254x supports IPv4/TCP/UDP checksumming and TCP segmentation in hardware.  The wm driver supports these features of the chip.  See
     ifconfig(8) for information on how to enable this feature.

HISTORY

     The wm driver first appeared in NetBSD 1.6.

AUTHORS

     The wm driver was written by Jason R. Thorpe <thorpej@wasabisystems.com>.

BUGS

     The Intel i82545GM and i82546GB controllers with internal SERDES are not currently supported.

NAME

     ixgb -- Intel(R) PRO/10GbE Ethernet driver for the FreeBSD operating system

SYNOPSIS

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

	   device ixgb

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

	   if_ixgb_load="YES"

DESCRIPTION

     The ixgb driver provides support for PCI Gigabit Ethernet adapters based on the Intel 82597EX Ethernet controller chips.  The driver supports
     Transmit/Receive checksum offload and Jumbo Frames.

     For questions related to hardware requirements, refer to the documentation supplied with your Intel PRO/10GbE adapter.  All hardware require-
     ments 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 16114.

     This driver version supports VLANs.  For information on enabling VLANs, see ifconfig(8).

HARDWARE

     The ixgb driver supports the following cards:

     o	 Intel PRO/10GbE LR Server Adapter
     o	 Intel PRO/10GbE SR Server Adapter

DIAGNOSTICS

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

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

     ixgb%d: watchdog timeout -- resetting  The device has stopped responding to the network, or there is a problem with the network connection
     (cable).

SUPPORT

     For general information and support, go to the Intel support website at: http://support.intel.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 <freebsd@intel.com>.
