    As far as I'm aware the ATM layer doesn't care what happens to the
    SKB after it gets passed to netif_rx(), so I don't know why this would
    be a problem. Some people seem to be suggesting that we need to zero
    out ->cb before passing the SKB to netif_rx() but I don't see why
    that would be neccesary.
