Overview

This chapter discusses the Linux drivers for the Broadcom NetXtreme II network adapters and describes how to install them. For a description of the drivers, see Table 4.

Table 4. Broadcom NetXtreme II Linux Drivers

Linux Driver	Description
bnx2	Indicates the Linux drivers for the AT-2973SX
cnic	AT-2973T, and AT-2973T/4 network adapters.
	The bnx2 driver is the networking driver and
	the cnic driver supports additional features
	required by the bnx2i iSCSI offload driver. The
	bnx2i iSCSI driver is packaged separately.
bnx2i	Indicates the Linux driver that enables iSCSI
	offload on the AT-2973SX, AT-2973T, and AT-
	2973T/4 network adapters.

Limitations This section describes the testing limitations of the following Linux drivers:

bnx2 Driver

The current version of the driver has been tested on 2.4.x kernels (starting from 2.4.24) and all 2.6.x kernels. The driver may not compile on kernels older than 2.4.24.

Testing is concentrated on i386 and x86_64 architectures. Only limited testing has been done on other architectures. You may need to make minor changes to some source files and the Makefile on some kernels. In addition, the Makefile does not compile the cnic driver on kernels older than 2.6.16. iSCSI offload is only supported on 2.6.16 and newer kernels.

Support for the 2.4.21 kernels is provided in Red Hat Enterprise Linux 3.
