IXG(4)                       Device Drivers Manual                      IXG(4)

NAME
     ixg - Intel(R) 10Gb Ethernet driver

SYNOPSIS
     ixg* at pci? dev ? function ?

DESCRIPTION
     The ixg driver provides support for PCI 10Gb Ethernet adapters based on
     the Intel(R) 82598EB, 82599, X540 and X550 Ethernet Controllers.  The
     driver supports Jumbo Frames, TCP Segmentation Offload (TSO).

     For questions related to hardware requirements, refer to the
     documentation supplied with your Intel 10GbE adapter.  All hardware
     requirements listed apply to use with NetBSD.

     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.  On NetBSD,
     the maximum MTU size for Jumbo Frames is 9000 bytes.

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

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

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

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

HISTORY
     The ixg device driver comes from FreeBSD, where it is called ixgbe.  It
     first appeared in NetBSD 6.0.

AUTHORS
     The ixg driver was written by Intel Corporation
     <freebsdnic@mailbox.intel.com>.  It was imported from FreeBSD into NetBSD
     by David Young <dyoung@NetBSD.org>.

BUGS
     The hardware supports a maximum MTU of 16114 bytes, but the NetBSD port
     of the driver supports only 9000 bytes.
