系统:CentOS 5.5 X86_64、RHEL 5.6 X86_64
硬件:Dell R610、R710、R720
通过升级系统自带网卡驱动程序到最新版本,可以解决当网卡流量过大时,出现掉包、断网现象。

升级步骤:
1.查看当前网卡类型

# /sbin/lspci |grep Ethernet

02:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM5709 Gigabit Ethernet (rev 20)
02:00.1 Ethernet controller: Broadcom Corporation NetXtreme II BCM5709 Gigabit Ethernet (rev 20)
03:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM5709 Gigabit Ethernet (rev 20)
03:00.1 Ethernet controller: Broadcom Corporation NetXtreme II BCM5709 Gigabit Ethernet (rev 20)

2.查看网卡驱动模块

# cat /etc/modprobe.conf|grep eth
alias eth0 bnx2    #–>网卡模块为bnx2
alias eth1 bnx2
alias eth2 bnx2
alias eth3 bnx2

3.查看网卡驱动当前版本

# modinfo bnx2
filename:       /lib/modules/2.6.18-238.el5/kernel/drivers/net/bnx2.ko
version:        2.0.8-rh     #–>现有驱动的版本

4.下载最新网卡驱动程序
到以下链接,根据查询到的网卡型号下载最新的驱动程序:
http://zh-cn.broadcom.com/support/ethernet_nic/downloaddrivers.php

5.驱动程序安装

unzip linux-7.2.20.zip
cd Server/Linux/Driver/
rpm -ivh netxtreme2-7.2.20-1.src.rpm
cd /usr/src/redhat/SPECS/
rpmbuild -bb netxtreme2.spec
cd ../RPMS/x86_64/
rpm -ivh netxtreme2-7.2.20-1.x86_64.rpm

6.加载最新驱动模块

#vi change.sh
rmmod bnx2
modprobe bnx2

执行脚本:

sh change.sh

7.查看最新驱动版本

#modinfo bnx2
