Chapter 6: Installing the Linux Drivers
66
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.
Limitations This section describes the testing limitations of the following Linux drivers:
“bnx2 Driver” on page 66
“bnx2i Driver” on page 67
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.

Linux Driver Description
bnx2
cnic
Indicates the Linux drivers for the AT-2973SX
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.
