following command:

lspci -vvv -d 4040

For Windows-based systems, execute the

following sequence:

1. Right-click on My Computer

2. Select Manage;

3. Select Device Manager;

4. Check under Other devices for an

unknown device;

5. Right-click and select Properties for the

unknown device;

6. Select the Details tab and look for

VEN_4040 as part of the string.

Driver Installation

1. Unzip the provided NIC driver files to a

directory.

2. From the Device Manager, scan for new

hardware.

3. When prompted to connect to Windows

Update, Click No, not at this time, then

click Next.

4. In the next window, click Install from a

list of specific location and then click

Next.

5. Select Search for the best driver in these

locations. Select Include this location in

the search.

6. Provide the path to the directory where

the driver nxp2nic.sys3is located.

NIC Card Configuration

1. Open the Network Connections window

from the Control Panel.

2. Verify that NetXen NIC adapter icon says

Connected.

If not, right-click on the NIC Adapter

icon and select Properties, then assign

the IP and subnet addresses and click OK.

3. Use the x86 directory for 32-bit operating systems, and the x64 directory for 64-bit operating systems.

Driver Installation (tar.gz)

1. Untar the file, build, install, and load the

driver:

tar xzf [version].tar.gz

cd [version]

make

make install

modprobe nx_nic

NIC Card Configuration

1. Identify the NetXen Ethernet interface:

cat /proc/net/nx_nic/dev0 | grep eth

2. Assign an IP address:

ifconfig eth[n] [IP address]

3. Quick-Start Installation Instructions

NetXen, Inc. Intelligent NIC Installation and Tuning Guide 5

If a NetXen Intelligent NIC card is already installed on the system and a driver and/or

firmware update is required, refer to the procedure in Table 6 below.

Table 6 Quick Start Instructions — Updating from an Existing Driver and Firmware

Windows Driver/Firmware Update1

1. Refer to Section 4.1 for more information on firmware tools and guidelines.

Linux Driver/Firmware Update1VMware Firmware Update2

2. Refer to Section 4.4 for more information on VMware pre-installation guidelines

Verify Link Status

1. With the existing driver and firmware

installed, verify that the interface is up

before continuing with the firmware

update.

Update to New Firmware

1. Open a Command window.

2. Go to the utils directory in the driver

package provided.

3. The following binaries are required to be

in the same directory from where the

Flash command will be executed:

nxflash.exe

xfp_romimage

cx4_romimage

4. Run the following commands:

nxflash -i NX_NIC --all3

5. Verify the firmware has been updated

using the following command.

nxflash -i NX_NIC --info

Update to the New Driver

1. Install the new driver version.

2. Verify the new driver version.

3. Reboot the system after the firmware

update.

3. Writing of the Flash is a critical operation. Please do not interrupt or reboot during this time.

Verify Link Status

1. With the existing driver and firmware

installed, verify that the interface is up

using ifconfig before continuing with the

firmware update.

Update to New Firmware

1. Run the following command from the bin

directory of the driver:

./nxflash -i eth[n] --all3

Unload and Remove the Existing

Driver

1. Unload the existing driver.

ifconfig eth[n] down

rmmod nx_nic

2. Remove the existing driver module.

rm -f /lib/modules/[kernel version]/

kernel/

drivers/net/nx_nic.ko4

Reboot the System

1. After the new firmware has been flashed

and the old firmware has been removed,

reboot the system.

Update to the New Driver

1. Update to the new driver as follows:

tar xzf [version].tar.gz

cd [version]

make

make install

modprobe nx_nic

2. Ensure that the Ethernet interface is up.

ifconfig eth[n] <ip addr> up

4. For Linux kernel 2.4, the driver will appear as a nx_nic.o file.

Firmware Update Methods

There are three ways to perform a firmware

update in VMware.

1. Using a non-virtualized Linux OS host.

2. Using a non-virtualized Windows OS

host.

3. Using the NetXen LiveCD.

For a VMware firmware update using a non-

virtualized Linux OS, first perform the steps

listed in the rightmost column of Table 5

above, “Linux NIC Driver Installation”.

Next perform the steps listed in the middle

column of Table 6, “Linux Driver/Firmware

Update”.

For a VMware firmware update using a non-

virtualized Windows OS, first perform the

steps listed in the middle column of Table 5

above, “Windows NIC Driver Installation”.

Next perform the steps listed in the leftmost

column of Table 6, “Windows Driver/

Firmware Update”.

For a firmware update using the NetXen

LiveCD, download the NetXen LiveCD5

ISO image and burn that image onto a CD

and boot the system with the CD. Use option

2 from the LiveCD menu shown below to

update the flash on the card.

NetXen LiveCD Firmware Update

Menu Options:

1. Show NetXen board information

2. Update to latest firmware on NetXen

board

3. Reboot system if firmware has been

updated

Enter here:

5. Refer to the support page on the on NetXen web site for more information on downloading the LiveCD.

3. Quick-Start Installation Instructions

Once the WIndows or Linux NIC installation is complete as described in the previous tables, the following

procedures in Table 7 can be used to enable the Linux LSA driver.

Table 7 Quick Start Instructions — Enabling Linux LSA Driver

Enabling Linux LSA Driver

Note: the Linux NIC driver must be installed before executing the procedure below.

1. Untar the file, build, and load the drivers.

tar xzf [version]-lsa.tar.gz

cd [version]-lsa

make

cd driver

insmod ./nx_intercept.ko

insmod ./nx_lsa.ko

2. To verify the LSA driver is operating, execute the following command:

cat /proc/net/nx_nic/lsa_1/stats

3. Example for offloading iperf.

cd ../nxoffload

./nxoffload –a –n iperf

4. To display the current offload rules execute the following:

./nxoffload -s
