--到http://www.broadcom.com/support/ethernet_nic/netxtreme_server.php 下载5720驱动

--安装驱动
The following are general guidelines for installing the driver.

  1. Install the source RPM package:

    rpm -ivh tg3-.src.rpm

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

    cd /usr/src/{redhat,OpenLinux,turbo,packages,rpm ..}

========
在过去RHEL5以及之前的版本会在/usr/src/redhat下SOURCE 和SPECS这两个目录

现在rhel6是找不到这个目录的

默认情况下会在/root/下生成一个rpmbuild的目录这个下面就有SOURCE 和SPECS着两个目录

安装软件包后就会到这两个目录中去

rpm -bb SPECS/tg3.spec

or

rpmbuild -bb SPECS/tg3.spec (for RPM version 4.x.x)
Note that the RPM path is different for different Linux distributions.

The driver will be compiled for the running kernel by default. To build
the driver for a kernel different than the running one, specify the
kernel by defining it in KVER:

rpmbuild -bb SPECS/tg3.spec --define "KVER "

where in the form. of 2.x.y-z is the version of another
kernel that is installed on the system.

  1. Install the newly built package (driver and man page):
    (/root/rpmbuild/RPMS/x86_64)
    rpm -ivh RPMS//tg3-..rpm

is the architecture of the machine, e.g. i386:

rpm -ivh RPMS/i386/tg3-.i386.rpm

Note that the --force option may be needed on some Linux distributions
if conflicts are reported.

The driver will be installed in the following path:
2.6.x/3.x kernels:

/lib/modules//kernel/drivers/net/tg3.ko

  1. Load the driver:

    insmod tg3.o
    or
    insmod tg3.ko (on 2.6.x/3.x kernels)
    or
    modprobe tg3

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

This version of the tg3 driver supports one module parameter that is
not available in the in-kernel driver. The parameter is named tg3_disable_eee.
To disable Energy Efficient Ethernet (EEE) support, set this module parameter
to 1.

The rest of the sections below apply to both the in-kernel tg3
driver and the tg3 driver package from Broadcom.

Driver settings can be queried and changed using ethtool. The latest ethtool
can be downloaded from ftp://ftp.kernel.org/pub/software/network/ethtool if
it is not already installed. The following are some common examples on how to
use ethtool. See the ethtool man page for more information. ethtool settings
do not persist across reboot or module reload. The ethtool commands can be put
in a startup script. such as /etc/rc.local to preserve the settings across a
reboot. On Red Hat distributions, "ethtool -s" parameters can be specified
in the ifcfg-ethx scripts using the ETHTOOL_OPTS keyword. The specified
ethtool parameters will be set during ifup. Example:
/etc/sysconfig/network-scripts/ifcfg-eth0:

ETHTOOL_OPTS="wol g speed 100 duplex half autoneg off"

Some ethtool examples:

  1. Show current speed, duplex, and link status:

    ethtool eth0

  2. Change speed, duplex, autoneg:

Example: 100Mbps half duplex, no autonegotiation:

ethtool -s eth0 speed 100 duplex half autoneg off

Example: Autonegotiation with full advertisement:

ethtool -s eth0 autoneg on

Example: Autonegotiation with 100Mbps full duplex advertisement only:

ethtool -s eth0 speed 100 duplex full autoneg on

  1. Show flow control settings:

    ethtool -a eth0

  2. Change flow control settings:

Example: Turn off flow control

ethtool -A eth0 autoneg off rx off tx off

Example: Turn flow control autonegotiation on with tx and rx advertisement:

ethtool -A eth0 autoneg on rx on tx on
Note that this is only valid if speed is set to autonegotiation.

  1. Show offload settings:

    ethtool -k eth0

  2. Change offload settings:

Example: Turn off TSO (TCP segmentation offload)

ethtool -K eth0 tso off

  1. Get statistics:

    ethtool -S eth0

  2. Perform. self-test:

    ethtool -t eth0

    Note that the interface (eth0) must be up to do all tests.

  3. Show number of channels (rings):

    ethtool -l eth0

    Note that this is only supported on newer MSI-X capable devices (e.g.
    57765, 57766, 5717, 5719, 5720) and available on 3.x kernels and 3.x
    ethtool only.
