I've customized ethtool source, it's giving the correct values depends on the real
physical I/F BW. (as per my requirements)

I need only speed from that.

As of my understanding, are the below lines right?

DEVICE BW = Real physical bandwidth of the device

So, Here DEVICE means only the Interface, not the Link, am i right?
    
Yes.
&

RATE = Rate assigned to perticular user/network/service.

How much the user/network/service can aquire max. allowable rate?
    
Yes.  If you add the bounded parameter, you create a maximum for that class.
I can consider as 10/100 Mbps for ethernet interface.
So, how about, when i use ppp0 (pppoe) in my CBQ, is it same?
bcoz, pppoe uses eth0, am i right?
    
I'm not sure about that.  But I think you have to use the eth0 speed.
Or use htb, no more bandwidth questions needed :)
Yah, from now onwards, no more DEVICE BW questions.
