Introduction
============

This file describes the Linux driver for the Broadcom NetXtreme BCM5700
series 10/100/1000 Mbps Ethernet Network Controllers.


Limitations
===========

The current version of the driver has been tested on the latest Red Hat
and United Linux distributions, as well as other similar Linux distributions
for i386, ia64, and x86_64 CPU architectures using 2.4.x kernels. The
driver has been tested up to kernel version 2.4.20.

The driver should work on other little endian or big endian CPU architectures,
but only very limited testing has been done on some of these machines. The
Makefile may have to be modified to include architecture specific compile
switches, and some minor changes in the source files may also be required.
On these machines, patching the driver into the kernel is recommended (see
below for instructions).


Packaging
=========

The driver is released in two packaging formats: source RPM and compressed tar
formats. The file names for the two packages are bcm5700-<version>.src.rpm and
bcm5700-<version>.tar.gz respectively. Identical source files to build the
driver are included in both packages. The tar file contains additional
utilities such as patches and driver diskette images for network installation.


Installing Source RPM Package
=============================

1. Install the source RPM package:

   rpm -ivh bcm5700-<version>.src.rpm

If installing the driver on SuSE Linux, refer to the Notes section below
before continuing.

2. CD to the RPM path and build the binary driver for your kernel:

   cd /usr/src/{redhat,OpenLinux,turbo,packages,rpm ..}
   rpm -bb SPECS/bcm5700.spec

or

   rpmbuild -bb SPECS/bcm5700.spec (for RPM version 4.x.x)

Note that the RPM path is different for different Linux distributions.

3. Install the newly built package (driver and man page):

   rpm -ivh RPMS/i386/bcm5700-<version>.i386.rpm

Note that the --force option is needed if installing on Red Hat 7.1, 7.2,
and others that already contain an older version of the driver.

The driver will be installed in the following path:

2.2.x kernels:

    /lib/modules/<kernel_version>/net/bcm5700.o

2.4.x kernels:

    /lib/modules/<kernel_version>/kernel/drivers/net/bcm5700.o

2.4.x kernels with bcm5700 driver patched in (e.g. Red Hat 7.1, 7.2):

    /lib/modules/<kernel_version>/kernel/drivers/net/bcm/bcm5700.o

or

    /lib/modules/<kernel_version>/kernel/drivers/addon/bcm5700/bcm5700.o

4. Load the driver:

   insmod bcm5700

If loading the driver on Red Hat 7.3, 2.1 AS or newer Red Hat kernels, refer
to the Notes section below before loading the driver.

5. To configure network protocol and address, refer to various Linux
documentations.

Building Driver From TAR File
=============================

1. Create a directory and extract the files:

   tar xvzf bcm5700-<version>.tar.gz

If installing the driver on SuSE Linux, refer to the Notes section below
before continuing.

2. Build the driver bcm5700.o as a loadable module for the running kernel:

   cd src
   make

3. Test the driver by loading it: 

   insmod bcm5700.o

If loading the driver on Red Hat 7.3, 2.1 AS or newer Red Hat kernels, refer
to the Notes section below before loading the driver.

4. Install the driver and man page:

   make install

See RPM instructions above for the location of the installed driver.

5. To configure network protocol and address, refer to various Linux
documentations.

Notes
=====

Note 1: If compiling the driver for a SuSE Linux kernel and errors are
reported, follow the general guidelines below to rebuild the kernel
source tree:

cd /usr/src/linux-<kernel_version>.SuSE
cp /boot/vmlinuz.config .config
cp /boot/vmlinuz.version.h include/linux/version.h
cp /boot/vmlinuz.autoconf.h include/linux/autoconf.h
make oldconfig
make dep

where <kernel_version> is the actual kernel version used in the SuSE
distribution. Example: /usr/src/linux-2.4.4.SuSE

Note 2: If loading the driver on Red Hat 7.3, Red Hat 2.1 AS, and other newer
kernels and patches, it is necessary to unload the tg3 driver first if it
is loaded. While tg3 is a fully functioning driver written by Red Hat et al,
Broadcom recommends users to use the bcm5700 driver written and tested by
Broadcom. Use ifconfig to bring down all eth# interfaces used by tg3 and do
the following to unload the tg3 driver:

rmmod tg3

It may also be necessary to manually edit the file /etc/modules.conf to
change an interface alias name from tg3 to bcm5700. Example:

alias eth0 tg3

Replace tg3 with bcm5700:

alias eth0 bcm5700

See the man pages for ifconfig, rmmod, modules.conf for more detailed
information. It is also recommended to apply the pci patch described in
the next section.


Patching PCI Files (Optional)
=============================

To use the Red Hat kudzu hardware detection utility, a number of files
containing PCI vendor and device information need to be patched with
information on the BCM5700 series NICs. Patch files for Red Hat 7.x
are included. Apply the appropriate patch by running the patch command.
For example, on Red Hat 7.2 for i386, apply the patch by doing the following:

   patch -N -p1 -d /usr < pci-rh72-i386.patch

Run kudzu:

   kudzu

Patching module-info Files (Optional)
=====================================

To use Red Hat's graphical network administration tool neat, the module-info
files need to be patched. Apply the appropriate patch by running the patch
command. For example, on Red Hat 8.0 for i386, apply the patch by doing the
following:

   patch -N -p1 -d /boot < modinfo-rh80-i386.patch

Run neat:

   neat

Patching Driver Into Kernel (Optional)
======================================

Patch files are included for patching the driver into some of the latest
2.4.x kernel source trees. This step is optional and should only be done
by users familiar with configuring and building the kernel. The patch
will modify the orginal kernel's source code.

Follow the following steps to patch the driver into kernel:

1. Select the patch file that matches your kernel and apply the patch:

   patch -p1 -d <kernel_src_root> < bcm5700-<version>-2.4.<x>.patch

where <version> is the version of the bcm5700 driver and 2.4.<x> is the
version of the kernel to patch (e.g. 2.4.10).

Note: <kernel_src_root> is usually /usr/src/linux or /usr/src/linux-2.4.<x>

2. Configure the kernel to include the bcm5700 driver. It can be found
under Network Device Support ---> Ethernet (1000 Mbit) ---> Broadcom BCM5700
support when make menuconfig is run. Select built-in or module for the driver:

   cd <kernel_src_root>
   make menuconfig 

3. Compile the kernel:

   make dep
   make clean
   ....
   ....


Network Installation
====================

For network installations through NFS, FTP, or HTTP (using a network boot
disk or PXE), a driver diskette that contains the bcm5700 driver is needed for
Red Hat 7.x. The driver diskette images for the most recent Red Hat versions
are included. Boot drivers for other Linux versions can be compiled by
modifying the Makefile and the make environment. Further information is
available from Red Hat's website.

To create the driver diskette, select the appropriate image file, gunzip it,
and do the following:

dd if=dd.img of=/dev/fd0H1440.


Unloading and Removing Driver
=============================

To unload the driver, use ifconfig to bring down all eth# interfaces opened
by the driver, then do the following:

rmmod bcm5700


If the driver was installed using rpm, do the following to remove it:

rpm -e bcm5700


If the driver was installed using make install from the tar file, the driver
bcm5700.o has to be manually deleted from the system. Refer to the section
"Building Driver From TAR File" for the location of the installed driver.


Module Parameters
=================

Optional parameters for the driver can be supplied as command line arguments 
to the insmod command. Typically, these parameters are set in the file
/etc/modules.conf (see the man page for modules.conf). These parameters take
the form

    <parameter>=value[,value,...]

where the multiple values for the same parameter are for multiple NICs
installed in the system.

Note that default or other meaningful values will be used when invalid values
are selected. Some combinations of parameter values may conflict and lead to
failures. The driver cannot detect all such conflicting combinations.

All the parameters are listed below.

line_speed

    Selects the line speed of the link. This parameter is used together with
    full_duplex and auto_speed to select the speed and duplexity of the link
    and the setting of autonegotiation.
    
    The valid values are:
    
    0      Autonegotiate for highest speed supported by link partner (default)
    10     10 Mbps
    100    100 Mbps
    1000   1000 Mbps

    If line_speed is set to 10, 100, or 1000, the NIC will autonegotiate for
    the selected speed (and selected duplexity) if auto_speed is set to 1.
    If auto_speed is set to 0, the selected speed and duplexity will be
    set without autonegotiation. Note that 1000 Mbps must be negotiated for
    copper twisted pair links.

auto_speed

    Enables or disables autonegotiation. The valid values are:

    0      Autonegotiation disabled
    1      Autonegotiation enabled (default)

    Note that this parameter is ignored and assumed 1 if line_speed is set
    to 0.
    
full_duplex

    Selects the duplexity of the link. This paramter is used together with
    line_speed to select the speed and duplexity of the link. Note that this
    parameter is ignored if line_speed is 0.
    
    The valid values are:
    
    0      half duplex
    1      full duplex (default)
    
    
rx_flow_control

    Enables or disables receiving flow control (pause) frames. This parameter
    is used together with auto_flow_control. The valid values are:
    
    0      pause receive disabled
    1      pause receive enabled if auto_flow_control is set to 0, or
           pause receive advertised if auto_flow_control is set to 1 (default)

tx_flow_control

    Enables or disables transmitting flow control (pause) frames. This parameter
    is used together with auto_flow_control. The valid values are:
    
    0      pause transmit disabled
    1      pause transmit enabled if auto_flow_control is set to 0, or
           pause transmit advertised if auto_flow_control is set to 1 (default)

auto_flow_control

    Enables or disables autonegotiation of flow control. This parameter is used
    together with rx_flow_control and tx_flow_control to determine the
    advertised flow control capability. The valid values are:
    
    0      flow control autonegotiation disabled
    1      flow control autonegotiation enabled with capability specified in
           rx_flow_control and tx_flow_control (only valid if line_speed is
           set to 0 or auto_speed is set to 1) (default)

mtu

    Enables jumbo frames up to the specified MTU size. The valid range for
    this parameter is 1500 to 9000. Default is 1500 which is standard
    ethernet (non-jumbo) MTU size. Note that the MTU size excludes the
    ethernet header size of 14 bytes. Actual frame size is MTU size + 14 bytes.
    Jumbo MTU sizes are not supported on BCM5705 chips.

    The MTU size can also be changed using ifconfig after the driver is loaded.
    See the ifconfig man page for details.

tx_checksum

    Enables or disables hardware transmit TCP/UDP checksum. The valid values
    are:

    0      checksum disabled
    1      checksum enabled (default)

rx_checksum

    Enables or disables hardware receive TCP/UDP checksum validation. The
    valid values are:

    0      checksum disabled
    1      checksum enabled (default)

scatter_gather

    Enables or disables scatter-gather and 64-bit DMA on x86. This option is
    only useful when running on TUX-enabled kernels or newer kernels with
    zero-copy TCP. The valid values are:

    0      scatter-gather and 64-bit DMA on x86 disabled
    1      scatter-gather and 64-bit DMA on x86 enabled (default)

tx_pkt_desc_cnt

    Configures the number of transmit descriptors. Default is 100. The
    valid range is from 1 to 600. Note that the driver may not be able to
    allocate the required amount of memory if this parameter is set too high.
    Depending on kernel and CPU architecture, each descriptor may require up
    to about 268 bytes. This parameter should not be set less than 80 if
    adaptive_coalesce (see below) is enabled.

rx_std_desc_cnt

    Configures the number of receive descriptors for frames up to 1528 bytes.
    Default is 200. The valid range is from 1 to 511. This parameter should
    not be set less than 80 on systems with high network traffic. Setting this
    parameter higher allows the NIC to buffer larger bursts of network
    traffic without dropping frames, especially on slower systems. Note that
    the driver may not be able to allocate the required amount of memory if
    this parameter is set too high. Depending on kernel and CPU architecture,
    each descriptor may require up to about 268 bytes. Each descriptor also
    requires a socket buffer of at least 1536 bytes. This parameter should not
    be set less than 50 if adaptive_coalesce (see below) is enabled.

rx_jumbo_desc_cnt

    Configures the number of receive descriptors for jumbo frames larger
    than 1528 bytes. Default is 128 and valid range is from 1 to 255.
    When jumbo frames larger than 1528 bytes are used, this parameter should
    not be set lower than 60 on systems with high network traffic. Setting
    this parameter higher allows the NIC to buffer larger bursts of jumbo
    traffic without dropping frames, especially on slower systems. Depending
    on kernel and CPU architecture, each descriptor may require up to about
    268 bytes. Each descriptor also requires a socket buffer the size of a
    maximum jumbo frame. On systems with insufficient memory, it may be
    necessary to reduce this parameter. This parameter should not be set less
    than 50 if adaptive_coalesce (see below) is enabled. When the maximum
    frame size is 1528 or smaller (MTU size 1514 or smaller), this parameter
    is not used and is always 0.

adaptive_coalesce

    Enables or disables adaptive adjustments to the various interrupt
    coalescing parameters. Enabling it allows the driver to dynamically
    adjust the interrupt coalescing parameters to achieve high throughput
    during heavy traffic and low latency during light traffic.
    rx_std_desc_cnt, (and rx_jumbo_desc_cnt if using jumbo frames) should not
    be set less than 50, and tx_pkt_desc_cnt should not be set less than 80
    when this parameter is enabled. The valid values are:

    0      disabled
    1      enabled (default)

rx_coalesce_ticks

    Configures the number of 1 usec ticks before the NIC generates receive
    interrupt after receiving a frame. This parameter works in conjunction
    with the rx_max_coalesce_frames parameter. Interrupt will be generated
    when either of these thresholds is exceeded. 0 means this parameter is
    ignored and interrupt will be generated when the rx_max_coalesce_frames
    threshold is reached. The valid range is from 0 to 500, and default is
    60. This parameter is not used and will be adjusted automatically if
    adaptive_coalesce is set to 1.

rx_max_coalesce_frames

    Configures the number of received frames before the NIC generates receive
    interrupt. The valid range is from 0 to 100, and default is 15. This
    parameter and rx_coalesce_ticks cannot be both 0, otherwise no receive
    interrupts will be generated. It should also be set lower than
    rx_std_desc_cnt (and rx_jumbo_desc_cnt if using jumbo frames). This
    parameter is not used and will be adjusted automatically if
    adaptive_coalesce is set to 1.

tx_coalesce_ticks

    Configures the number of 1 usec ticks before the NIC generates transmit
    interrupt after transmitting a frame. This parameter works in conjunction
    with the tx_max_coalesce_frames parameter. Interrupt will be generated
    when either of these thresholds is exceeded. 0 means this
    parameter is ignored and interrupt will be generated when the
    tx_max_coalesce_frames threshold is reached. The valid range is from 0 to
    500, and default is 200. This parameter is not used and will be adjusted
    automatically if adaptive_coalesce is set to 1.

tx_max_coalesce_frames

    Configures the number of transmitted frames before the NIC generates
    transmit interrupt. The valid range is from 0 to 100, and default is 35.
    This parameter and tx_coalesce_ticks cannot be both 0, otherwise no
    transmit completion interrupt will be generated. This parameter should
    always be set lower than tx_pkt_desc_cnt. This parameter is not used and
    will be adjusted automatically if adaptive_coalesce is set to 1.

stats_coalesce_ticks

    Configures the number of 1 usec ticks between periodic statistics block
    DMAs. The valid range is from 100 to 3600000000, and default is 1000000
    (1 sec.). 0 is also valid and is used to disable statistics updates.
    This parameter is not used and will be set to default if adaptive_coalesce
    is set to 1.

enable_wol

    Enables or disables magic packet Wake-On-LAN when the system is shutdown.
    Note that not all systems support Wake-On-LAN. The valid values are:

    0    magic packet Wake-On-LAN disabled (default)
    1    magic packet Wake-On-LAN enabled

enable_tso

    Enables or disables TCP Segmentation Option (TSO) when using kernels that
    support it.

    0    TSO disabled (default)
    1    TSO enabled


Driver Messages
===============

The following are the most common sample messages that may be logged in the file
/var/log/messages. Use dmesg -n <level> to control the level at which messages
will appear on the console. Most systems are set to level 6 by default.
