Network Driver (snull)

Hi everyone,

Can you explain me what snull is? I am developing network driver.

Thank you

    I guess you are reading the book about device drivers from O'Reilly.
    As far as I remember snull is an example network driver that creates 2 interfaces. It works like loopback split in 2 devices.
    Traffic send through one of the interfaces will be received at the other.

    The book was written for kernel 2.4. I don't know if the code still works without modifications.

    Hope it helps
