# ixgb(4)

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

## NAME

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

## SYNOPSIS

**device ixgb**

## 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 a list of supported adapters, see the *README* included with the driver.

For questions related to hardware requirements, refer to the documentation supplied with your Intel PRO/10GbE adapter. All hardware requirements 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)](/ifconfig/8.md) 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 the *README*.

## HARDWARE

The **ixgb** driver supports the following cards:

- Intel PRO/10GbE LR Server Adapter

- 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 additional information regarding building and installation, see the *README* included with the driver. For general information and support, go to the Intel support website at: *http://support.intel.com*.
