Packaging
=========
The driver is released in a source RPM format. The file name for
the package is bcm5700-<version>.src.rpm and is dependent on the
kernel source code. If you have not installed the kernel source
code and/or setup the source tree on your Linux system, refer to
the "Kernel Source Code Setup" section below.
Kernel Source Code Setup
========================
The bcm5700 driver requires the presence of the kernel source code
and configuring the kernel source before building the bcm5700 driver.
The following steps need to be done once for each kernel that is
booted. For example, if the current kernel is UP (uni-processor)
and an SMP (symmetrical-multi-processor) kernel is booted, these
steps must be performed again to configure the kernel source for
SMP before building the bcm5700 driver for the SMP kernel.
Red Hat Installation:
If the /usr/src/linux-<kernel-version> directory does not
exist, install the kernel source code per Red Hat instructions.
Once installed, follow the commands listed below to configure
the kernel source to match the running kernel.
# cd /usr/src/linux-<kernel_version>
# make mrproper
# make -e KERNELRELEASE=`uname -r` oldconfig
# make -e KERNELRELEASE=`uname -r` dep
UnitedLinux 1.0 Installation:
If the /usr/src/linux-<kernel-version> directory does not exist,
install the kernel source code per SUSE instructions.
Once installed, follow the commands listed below to set up
the kernel source tree.
# cd /usr/src/linux-<kernel_version>.SuSE
# make mrproper
# make cloneconfig
# make dep
SUSE SLES 7 Installation:
If the /usr/src/linux-<kernel-version> directory does not exist,
install the kernel source code per SUSE instructions.
Once installed, follow the commands listed below to set up
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
SUSE SLES 9 Installation:
If the /usr/src/linux-<kernel-version> directory does not exist,
install the kernel source code per SUSE instructions.
Once installed, follow the commands listed below to set up
the kernel source tree.
# cd /usr/src/linux-<kernel_version>
# make mrproper
# make cloneconfig
Installing the RPM Package
=============================
1. This package requires the kernel source code as well as
setting up the source tree. Verify the source code
/usr/src/linux-<kernel-version> directory exists.
# cd /usr/src/linux-<kernel-version>
If the kernel source code is not present, then
refer to the "Kernel Source Code Setup"
section.
2. Install the source RPM package.
# rpm -ivh bcm5700-<version>.src.rpm
3. Build the binary RPM for the bcm5700 driver.
Red Hat Installation:
# cd /usr/src/redhat
# rpmbuild -bb SPECS/bcm5700.spec
SUSE SLES 7 and UnitedLinux 1.0 Installations:
# cd /usr/src/packages
# rpm -bb SPECS/bcm5700.spec
SUSE SLES 9 Installations:
# cd /usr/src/packages
# rpmbuild -bb SPECS/bcm5700.spec
If you get an error during the build process,
refer to the "Kernel Source Code Setup" section to
correctly setup the source tree.
4. Check for the existence of a current version of the bcm5700 package as
follows:
# rpm -q bcm5700
If an old version of the package exists, the RPM package should be
removed.
# rpm -e bcm5700
Then remove the loaded bcm5700 module.
# rmmod bcm5700
Verify that the old bcm5700 package has been removed as follows:
# rpm -q bcm5700
5. Install the new RPM package. This installs the bcm5700 driver and man page.
Do not use the U (Upgrade) flag in the RPM command below - previous bcm5700
drivers must be removed as described in step 4 above before installing this
version.
# rpm -ivh RPMS/i386/bcm5700-<version>.i386.rpm --force
The bcm5700.o module is installed in the following directory:
Red Hat Linux 8.0
/lib/modules/<kernel_version>/kernel/drivers/net
Red Hat Linux 7.3
/lib/modules/<kernel_version>/kernel/drivers/net
Red Hat Linux 7.2
/lib/modules/<kernel_version>/kernel/drivers/net
Red Hat EL 3
/lib/modules/<kernel_version>/kernel/drivers/net
Red Hat EL 2.1
/lib/modules/<kernel_version>/kernel/drivers/addon/bcm5700
SUSE SLES 7
/lib/modules/<kernel_version>/kernel/drivers/net/bcm
UnitedLinux 1.0
/lib/modules/<kernel_version>/kernel/drivers/net/bcm
SUSE SLES 9
/lib/modules/<kernel_version>/kernel/drivers/net/bcm
For SLES 9 bcm5700.ko module will be installed instead of bcm5700.o
6. Configure your network setting and address. You may need to refer
to your Linux vendor documentation. Use the "netconfig" tool for
Red Hat configuration. Other helpful network configuration tools
such a "yast" in SLES 7 and UnitedLinux exist for easy configuration.
For SLES 9, the user has to specify the module as bcm5700 while configuring
the network. The module can be specified in Hardware Details of
Advanced configuration.
7. Ensure that the /etc/modules.conf file is configured similar to the
example listed below. The example below is presented as if more
than one adapter is present. If so, one eth# instance should exist
for each ethernet port. Refer to the modules.conf man page for more
information.
alias eth0 bcm5700
alias eth1 bcm5700
alias eth# bcm5700
For SLES 9, the configuration file is /etc/modprobe.conf or
/etc/modprobe.conf.local
8. You can now reboot your server. Upon reboot the network should
start with the bcm5700 driver loaded and the correct network
configuration. To verify that the bcm5700 driver is loaded, use
the following command.
# lsmod
If bcm5700 is listed then the bcm5700 driver loaded.
Note: By default Red Hat 8.0 and SLES 9 installs the tg3 driver.
If the tg3 driver is installed, unload the tg3 driver first.
Use ifconfig to bring down all eth# interfaces used by tg3.
# ifconfig eth# down
Now remove or unload the tg3 driver.
# rmmod tg3
You may also need to manually edit the /etc/modules.conf file to
change the driver from tg3 to bcm5700.
For SLES 9, the configuration file is /etc/modprobe.conf or
/etc/modprobe.conf.local
alias eth0 tg3
and replace tg3 with bcm5700:
alias eth0 bcm5700
Note: If the above entry does not exist, add it to the configuration file.
Load the bcm5700 driver:
# insmod bcm5700
or
# modprobe bcm5700
Note: It is prefered to use modprobe in SLES 9. The insmod command
may not work the way it worked in 2.4 kernels.
Use ifconfig to bring up the network with the new driver:
# ifconfig eth# up
Refer to the man pages for lsmod, ifconfig, rmmod, insmod, modprobe,
modules.conf and modprobe.conf for more detailed information.
Module Parameters
=================
The complete set of Module Parameters supported by the bcm5700 driver
is described in the README.TXT which is installed under the
appropriated directories as mentioned in the Introduction section.
Notes:
"mtu" parameter:
Enables jumbo frames if MTU is set equal to or greater than 1501.
The valid range for MTU is from 1500 to 9000. Default is standard
MTU size, 1500 (not a jumbo frame). Note: MTU size excludes the
Ethernet header size of 14 bytes. Actual frame size is
MTU size + 14 bytes.
"rx_jumbo_desc_cnt" parameter:
It is always advised to use a value of 15 or above for the module
parameter rx_jumbo_desc_cnt. At values lower than 15, it has been
observed that jumbo traffic causes the driver to hang.
forcing speed/duplex and the "auto_speed" parameter:
If the user tries to force a particular Speed/Duplex connection it must
be ensured that the "auto_speed" parameter is set equal to 0. The
default value for "auto_speed" is always 1 even when "line_speed" is
configured to auto-negotiate (0), as well as all other designated
speeds (10, 100, 1000). The reason for this parameter is to allow
the user to either auto-negotiate a particular speed (auto_speed=1)
or to force a particular speed (auto_speed=0). The examples below
show "auto_speed" used in the two scenarios (auto negotiation vs. forced).
The command to auto-negotiate 100Mbs/Half duplex:
#insmod bcm5700 line_speed=100 full_duplex=0 auto_speed=1
The command to force 100Mbs/Half duplex:
#insmod bcm5700 line_speed=100 full_duplex=0 auto_speed=0
Note: For SLES 9, instead of insmod, modprobe has to be used.
tx_flow_control and rx_flow_control parameters:
If the tx_flow_control parameter is set to 1, the resulting
behaviour for the pause transmit is best explained as follows
If auto_flow_control=0 and auto_speed=0, pause transmit is
enabled and not advertised. If auto_flow_control=0 and auto_speed=1
Pause transmit is always enabled and advertised. If both auto_flow_control
and auto_speed are set to 1, then pause transmit is advertised for
autonegotiation.
The same explanation would apply to the pause receive behaviour if
the rx_flow_control parameter is set to 1.
Driver Messages
===============
The following are the most common sample messages that may be logged in
the file /var/log/messages. Some Linux distributions may not display
messages to the console. To set messages to display on the console,
at the command line use the following to control the level at which messages
will appear on the console.
# dmesg -n 6
Most systems are set to level 6 by default. For Example, if an HP NC7771
Gigabit Server Adapter is installed, the set of messages would look
as follows:
eth#: HP NC7771 Gigabit Server Adapter found at mem c6ff0000,
IRQ 5, node addr 00101804088e
eth#: Broadcom BCM5703 Integrated Copper transceiver found
eth#: Scatter-gather ON, 64-bit DMA ON, Tx Checksum ON, Rx Checksum ON
If an HP NC6770 Gigabit Server Adapter is installed, the set of messages
would look as follows:
eth#: HP NC6770 Gigabit Server Adapter found at mem c6fe0000,
IRQ 10, node addr 000802280026
eth#: Agilent HDMP-1636 SerDes transceiver found
eth#: Scatter-gather ON, 64-bit DMA ON, Tx Checksum ON, Rx Checksum ON
Link up and speed indication
bcm5700: eth# NIC Link is Up, 1000 Mbps full duplex
Link down indication
bcm5700: eth# NIC Link is Down
Statistics
==========
Detailed statistics and configuration information can be viewed by:
# more /proc/net/nicinfo/eth#.info.
Limitations
===========
The /proc/net/nicinfo/eth#.info file may report incorrect information
regarding statistics and PCI slot. Note that in some cases
more tx_packets and/or rx_packets are reported than tx_bytes
and/or rx_bytes, respectively. The reason for the error is due
to counters rolling over. Also note that "PCI_SLOT" is not the
actual physical slot. "PCI_SLOT" represents the PCI device ID.
Under lower speed and half duplex combinations, a higher error count may
be generated. This error will have minimal effect on the overall system
and session performance. Some error count generation is a normal and
expected occurrence in these conditions.
Uninstalling the RPM Package
=============================
The following command will uninstall the bcm5700 RPM.
# rpm -e bcm5700-<version>
