    wrap copy in 8139too.c


    I came across a function wrap_copy on Linux Cross Reference - Free Electrons
    I came across a function wrap_copy on
    add http to following text
    Code:
    lxr.free-electrons.com/source/drivers/net/8139too.c
    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?

    I can be found either 40 miles west of Chicago, in Chicago, or in a galaxy far, far away.

    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>
    Sometimes, real fast is almost as good as real time.
