Is there a possibility that I can hardcode interface name(say eth1) to a specific interface in the linux driver code?
This is in a controlled environemnt only, so breaking from default linux way(dynamically assigning name) is ok.
You may not need to do that; you could instead just fiddle with the dynamic assignment mechanism. udev has configuration files that control how names are assigned to devices, and if I remember it will also allow you to create links with handy names for given device names... so you can probably achieve your effect by re-configuring rather than re-coding.
Check out the man page and docs for udev.
