In This Release
|
||||
===============
|
||||
|
||||
This file describes the FreeBSD* driver, version 1.3.x, for the Intel(R)
|
||||
PRO/1000 Family of Adapters. This driver has been developed for use with
|
||||
FreeBSD, version 4.5.
|
||||
|
||||
The driver supports Transmit/Receive Checksum Offload and Jumbo Frames on
|
||||
all but the 82542-based adapters. For specific adapters, refer to the
|
||||
Supported Adapters section below.
|
||||
|
||||
Support for VLANs has been added as a new feature in this driver version.
|
||||
|
||||
For questions related to hardware requirements, refer to the documentation
|
||||
supplied with your Intel PRO/1000 adapter. All hardware requirements listed
|
||||
apply to use with FreeBSD.
|
||||
|
||||
|
||||
Supported Adapters
|
||||
==================
|
||||
|
||||
The following Intel network adapters are compatible with the drivers in this
|
||||
release:
|
||||
|
||||
Controller Adapter Name Board IDs
|
||||
---------- ------------ ---------
|
||||
|
||||
82542 PRO/1000 Gigabit Server Adapter 700262-xxx, 717037-xxx
|
||||
|
||||
82543 PRO/1000 F Server Adapter 738640-xxx, A38888-xxx,
|
||||
A06512-xxx
|
||||
|
||||
82543 PRO/1000 T Server Adapter A19845-xxx, A33948-xxx
|
||||
|
||||
82544 PRO/1000 XT Server Adapter A51580-xxx
|
||||
|
||||
82544 PRO/1000 XF Server Adapter A50484-xxx
|
||||
|
||||
82544 PRO/1000 T Desktop Adapter A62947-xxx
|
||||
|
||||
82540 PRO/1000 MT Desktop Adapter A78708-xxx
|
||||
|
||||
82545 PRO/1000 MT Server Adapter A92165-xxx
|
||||
|
||||
82545 PRO/1000 MF Server Adapter A91622-xxx
|
||||
|
||||
82545 PRO/1000 MF Server Adapter(LX) A91624-xxx
|
||||
|
||||
82546 PRO/1000 MT Dual Port Server Adapter A92111-xxx
|
||||
|
||||
82546 PRO/1000 MF Dual Port Server Adapter A91620-xxx
|
||||
|
||||
|
||||
To verify your Intel adapter is supported, find the board ID number on the
|
||||
adapter. Look for a label that has a barcode and a number in the format of
|
||||
123456-001 (six digits hyphen three digits). Match this to the list of
|
||||
numbers above.
|
||||
|
||||
For more information on how to identify your adapter, go to the Adapter &
|
||||
Driver ID Guide at:
|
||||
|
||||
http://support.intel.com/support/network/adapter/pro100/21397.htm
|
||||
|
||||

||||

|
||||
|
||||
|
||||
Building and Installation
|
||||
=========================
|
||||
|
||||
NOTE: You must have kernel sources installed in order to compile the driver
|
||||
module.
|
||||
|
||||
In the instructions below, x.x.x is the driver version as indicated in
|
||||
the name of the driver tar.
|
||||
|
||||
|
||||
1. Move the base driver tar file to the directory of your choice. For
|
||||
example, use /home/username/em or /usr/local/src/em.
|
||||
|
||||
2. Untar/unzip the archive:
|
||||
|
||||
tar xfz em-x.x.x.tar.gz
|
||||
|
||||
3. To load the driver onto a running system:
|
||||
|
||||
cd em-x.x.x/modules
|
||||
kldload ./if_em.ko
|
||||
|
||||
4. To assign an IP address to the interface, enter the following:
|
||||
|
||||
ifconfig em<interface_num> <IP_address>
|
||||
|
||||
5. Verify that the interface works. Enter the following, where <IP_address>
|
||||
is the IP address for another machine on the same subnet as the interface
|
||||
that is being tested:
|
||||
|
||||
ping <IP_address>
|
||||
|
||||
6. If you want the driver to load automatically when the system is booted:
|
||||
|
||||
cd em-x.x.x/modules
|
||||
cp if_em.ko /modules
|
||||
|
||||
Edit /boot/loader.conf, and add the following line:
|
||||
|
||||
if_em_load="YES"
|
||||
|
||||
OR
|
||||
|
||||
compile the driver into the kernel (see item 7).
|
||||
|
||||
|
||||
Edit /etc/rc.conf, and create the appropriate ifconfig_em<interface_num>
|
||||
entry:
|
||||
|
||||
ifconfig_em<interface_num>="<ifconfig_settings>"
|
||||
|
||||
Example usage:
|
||||
|
||||
ifconfig_em0="inet 192.168.10.1 netmask 255.255.255.0"
|
||||
|
||||
NOTE: For assistance, see the ifconfig man page.
|
||||
|
||||
7. If you want to compile the driver into the kernel, enter:
|
||||
|
||||
mkdir /usr/src/sys/dev/em
|
||||
cd em-x.x.x/src
|
||||
cp if_em* /usr/src/sys/dev/em
|
||||
mkdir /usr/src/sys/modules/em
|
||||
cp Makefile /usr/src/sys/modules/em
|
||||
|
||||
Edit Makefile at /usr/src/sys/modules to add the em subdirectory.
|
||||
|
||||
Edit your config file and add the following line, if it is not already
|
||||
in the file:
|
||||
|
||||
device em
|
||||
|
||||
Edit your config file, and remove the 'device wx' line from the file.
|
||||
|
||||
Edit the /usr/src/sys/conf/files.i386 file, and add the following lines:
|
||||
|
||||
dev/em/if_em.c optional em
|
||||
dev/em/if_em_hw.c optional em
|
||||
|
||||
Remove the following files from the /usr/src/sys/conf/files.i386 file, if
|
||||
they exist:
|
||||
|
||||
/dev/em/if_em_fxhw.c
|
||||
/dev/em/if_em_phy.c
|
||||
|
||||
Compile and install the kernel.
|
||||
|
||||
|
||||
Speed and Duplex Configuration
|
||||
==============================
|
||||
|
||||
By default, the adapter auto-negotiates the speed and duplex of the
|
||||
connection. If there is a specific need, the ifconfig utility can be used to
|
||||
configure the speed and duplex settings on the adapter. Example usage:
|
||||
|
||||
ifconfig em<interface_num> <IP_address> media 100baseTX mediaopt
|
||||
full-duplex
|
||||
|
||||
NOTE: Only use mediaopt to set the driver to full-duplex. If mediaopt is
|
||||
not specified and you are not running at gigabit speed, the driver
|
||||
defaults to half-duplex.
|
||||
|
||||
|
||||
This driver supports the following media type options:
|
||||
|
||||
autoselect - Enables auto-negotiation for speed and duplex.
|
||||
|
||||
10baseT/UTP - Sets speed to 10 Mbps. Use the ifconfig mediaopt
|
||||
option to select full-duplex mode.
|
||||
|
||||
100baseTX - Sets speed to 100 Mbps. Use the ifconfig mediaopt
|
||||
option to select full-duplex mode.
|
||||
|
||||
1000baseTX - Sets speed to 1000 Mbps. In this case, the driver
|
||||
supports only full-duplex mode.
|
||||
|
||||
1000baseSX - Sets speed to 1000 Mbps. In this case, the driver
|
||||
supports only full-duplex mode.
|
||||
|
||||
For more information on the ifconfig utility, see the ifconfig man page.
|
||||
|
||||
|
||||
Additional Configurations
|
||||
=========================
|
||||
|
||||
Jumbo Frames
|
||||
------------
|
||||
|
||||
To enable Jumbo Frames, use the ifconfig utility to increase the MTU
|
||||
beyond 1500 bytes.
|
||||
|
||||
NOTE: Only enable Jumbo Frames if your network infrastructure supports
|
||||
them.
|
||||
|
||||
The MTU range for Jumbo Frames is 1500 to 16114. For example, enter the
|
||||
following:
|
||||
|
||||
ifconfig em<interface_num> mtu 9000
|
||||
|
||||
VLANs
|
||||
-----
|
||||
|
||||
To enable VLANs in the kernel, modify the config file as follows:
|
||||
|
||||
pseudo-device vlan <num_VLANs>
|
||||
|
||||
Then, recompile the kernel and reboot.
|
||||
|
||||
To see the VLAN device entries, use ifconfig.
|
||||
|
||||
To attach a VLAN to the driver enter the following:
|
||||
|
||||
ifconfig vlan0 inet 10.0.0.1 netmask 255.255.255.0 vlan 1 vlandev
|
||||
em0 mtu 1500 up
|
||||
|
||||
Also, bring the driver up by entering:
|
||||
|
||||
ifconfig em0 up
|
||||
|
||||
|
||||
Known Limitations
|
||||
=================
|
||||
|
||||
There are known performance problems with this driver when running UDP
|
||||
traffic with Jumbo Frames. Intel recommends not using Jumbo Frames for UDP
|
||||
traffic.

||||
