网卡不能正常使用？

我用得是intel得千兆网卡，主板集成，我用的 是 redhat 7.2今天编译了一下网卡驱动，能ping 通自己的ip但ping不通网关。我是按照下边的步骤做的：
1. Move the base driver tar file to the directory of your choice. For example,
use /home/username/e1000 or /usr/local/src/e1000.

2. Untar/unzip archive:

tar zxf e1000-x.x.x.tar.gz

3. Change to the driver src directory:

cd e1000-x.x.x/src/

4. Compile the driver module:

make install

The binary will be installed as:

/lib/modules/[KERNEL_VERSION]/kernel/drivers/net/e1000.o

The install locations listed above are the default locations. They may
not be correct for certain Linux distributions. For more information,
see the ldistrib.txt file included in the driver tar.

5. Install the module:

insmod e1000 <parameter>=<value>

6. Assign an IP address to the interface by entering the following, where
x is the interface number:

ifconfig ethx <IP_address>

7. Verify that the interface works. Enter the following, where <IP_address>
is the IP address for another machine on the same subnet as the interface
that is being tested:

ping <IP_address>
