Take a look at system-config-network.
If you don't know how to use it, Google is your friend.

Actually ethernet card is not working.the output of the following commands are as:-

00:0f.0 Ethernet controller: nVidia Corporation Unknown device 07dc (rev a2)

It is detected so it most likely is working, just not functioning because the driver isn't loaded.
Goto nVidia site and download the driver and install it.

This is the major drawback to using RHEL, hardware support. You can get it to correcly identify your hardware by using an updated pci.ids file.

The PCI ID Repository

You can locate the original with this command.

locate pci.ids

I would save the original as a back up, just in case.

This won't make your network card work, it will just make it easier to identify the correct driver for it. You would still need the driver from the manufacturer's web site.
