So that you will be able to see the code I am pointing to.
Can some one help to understand what it is doing.
What I interpret it is that some how the person is tying to copy
payload from DMA to sk buffer.Is this interpretation correct?
What exactly are we trying to achieve via wrap_copy function call?

Since this is a driver question, you should probably move the thread to the Kernel forum. However, I think you are correct it what it is doing. You could contact the code maintainer, if he is still accessible via the published email address in the code comments: Jeff Garzik <jgarzik@pobox.com>
