How to install suse12.1 Nic

How to install the suse12.1 NIC-general Linux technology-Linux technology and application information. For more information, see the following. NIC driver not identified when setting network
I do not know how to install the NIC driver after downloading it. I heard that I want to check the readme file, but I cannot understand it.
The content in readme is as follows:


This is the Linux device driver released for RealTek RTL8168B/8111B, RTL8168C/8111C, RTL8168CP/8111CP, RTL8168D/8111D Gigabit Ethernet controllers with PCI-Express interface.



-Kernel source tree (supported Linux kernel 2.6.x and 2.4.x)
-For linux kernel 2.4.x, this driver supports 2.4.20 and latter.
-Compiler/binutils for kernel compilation


Check whether the built-in driver, r8169.ko (or r8169.o for kernel 2.4.x), is installed.
# Lsmod | grep r8169

If it is installed, please remove it.
# Rmmod r8169
Note: If the built-in driver cannot removed by rmmod, please edit/etc/modprobe. conf and comment 'Alias eth0 r8169 '. Then, remmove it again or reboot your computer.

Unpack the tarball:
# Tar vjxf r8168-8.aaa.bb.tar.bz2

Change to the directory:
# Cd r8168-8.aaa.bb

If you are running the target kernel, then you shoshould be able to do:

# Make clean modules (as root or with sudo)
# Make install
# Depmod-
# Modprobe r8168

You can check whether the driver is loaded by using following commands.

# Lsmod | grep r8168
# Ifconfig-

If there is a device name, ethX, shown on the monitor, the linux
Driver is loaded. Then, you can use the following command to activate
The ethX.

# Ifconfig ethX up

, Where X = 0, 1, 2 ,...


1. Set manually
A. Set the IP address of your machine.

# Ifconfig ethX "the IP address of your machine"

B. Set the IP address of DNS.

Insert the following configuration in/etc/resolv. conf.

Nameserver "the IP address of DNS"

C. Set the IP address of gateway.

# Route add default gw "the IP address of gateway"

2. Set by doing configurations in/etc/sysconfig/network-scripts
/Ifcfg-ethX for Redhat and Fedora, or/etc/sysconfig/network
/Ifcfg-ethX for SuSE. There are two examples to set network
Events.

A. Fix IP address:
DEVICE = eth0
BOOTPROTO = static
ONBOOT = yes
TYPE = ethernet
NETMASK = 255.255.255.0
IPADDR = 192.168.1.1
GATEWAY = 192.168.1.254
BROADCAST = 192.168.1.255

B. DHCP:
DEVICE = eth0
BOOTPROTO = dhcp
ONBOOT = yes


There are two ways to modify the MAC address of the NIC.
1. Use ifconfig:

# Ifconfig ethX hw ether YY: YY

, Where X is the device number assigned by Linux kernel, and
YY: YY is the MAC address assigned by the user.

2. Use ip:

# Ip link set ethX address YY: YY

, Where X is the device number assigned by Linux kernel, and
YY: YY is the MAC address assigned by the user.



1. Force the link status when insert the driver.

If the user is in the path ~ /R8168, the link status can be forced
To one of the 5 modes as following command.

# Insmod./src/r8168.ko speed = SPEED_MODE duplex = DUPLEX_MODE autoneg = NWAY_OPTION

, Where
SPEED_MODE = 1000for 1000 Mbps
= 100for 100 Mbps
= 10for 10 Mbps
DUPLEX_MODE = 0for half-duplex
= 1for full-duplex
NWAY_OPTION = 0for auto-negotiation off (true force)
= 1for auto-negotiation on (nway force)
For example:

# Insmod./src/r8168.ko speed = 100 duplex = 0 autoneg = 1

Will force PHY to operate in 100 Mpbs Half-duplex (nway force ).

2. Force the link status by using ethtool.
A. Insert the driver first.
B. Make sure that ethtool exists in/sbin.
C. Force the link status as the following command.

# Ethtool-s ethX speed SPEED_MODE duplex DUPLEX_MODE autoneg NWAY_OPTION

, Where
SPEED_MODE = 1000for 1000 Mbps
= 100for 100 Mbps
= 10for 10 Mbps
DUPLEX_MODE = halffor half-duplex
= Fullfor full-duplex
NWAY_OPTION = offfor auto-negotiation off (true force)
= Onfor auto-negotiation on (nway force)

For example:

# Ethtool-s eth0 speed 100 duplex full autoneg on

Will force PHY to operate in 100 Mpbs Full-duplex (nway force ).


Transmitting Jumbo Frames, whose packet size is bigger than 1500 bytes, please change mtu by the following command.

# Ifconfig ethX mtu MTU

, Where X = 0, 1, 2,..., and MTU is configured by user.

RTL8168B/8111B supports Jumbo Frame size up to 4 kBytes.
RTL8168C/8111C and RTL8168CP/8111CP support Jumbo Frame size up to 6 kBytes.
RTL8168D/8111D supports Jumbo Frame size up to 9 kBytes.
