NAME
     ixgbe -- Intel(R) 10Gb Ethernet driver for the DragonFly BSD operating
     system

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

	   device ixgbe

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

	   if_ixgbe_load="YES"

DESCRIPTION
     The ixgbe driver provides support for PCI 10Gb Ethernet adapters based on
     the Intel 82598EB Intel(R) Network Connections.  The driver supports
     Jumbo Frames, MSIX, TSO, and RSS.

     For questions related to hardware requirements, refer to the documenta-
     tion supplied with your Intel 10GbE adapter.  All hardware requirements
     listed apply to use with DragonFly.

     Support for Jumbo Frames is provided via the interface MTU setting.
     Selecting an MTU larger than 1500 bytes with the ifconfig(8) utility con-
     figures 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 ixgbe driver supports the following cards:

     *	 Intel(R) 10 Gigabit XF SR/AF Dual Port Server Adapter
     *	 Intel(R) 10 Gigabit XF SR/LR Server Adapter
     *	 Intel(R) 82598EB 10 Gigabit AF Network Connection
     *	 Intel(R) 82598EB 10 Gigabit AT CX4 Network Connection

PERFORMANCE
     The default DragonFly configuration may not give the best possible per-
     formance with single streams TCP connections.  Increasing the value of
     the net.inet.tcp.sosend_agglim sysctl to 12 or more will increase sending
     speeds.

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

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

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