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 and 82599 10 GbE Controllers.  The driver sup-
     ports 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).

HARDWARE

     The ixg driver supports the following cards:

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

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(4).  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.

     The hardware supports Message-Signalled Interrupts (MSI and MSI-X) and Receive-Side Scaling (RSS), however, these features are not enabled in
     the NetBSD driver at this time.
