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.conf5:

if_ixgb_load="YES"

DESCRIPTION

The ifconfig 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 requirements listed apply to use with Fx .

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 ifconfig 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: interrupt"
