If anyone has any objections, please let me know. ------------------ From: Larry Finger <Larry.Finger@...inger.net> commit fa16e5ea25d7dd83f663f333e70713aa2fa5dffe upstream. Some post-3.4 kernels have a problem when a cloned skb is used in the RX path. This patch handles one such case for r8712u. The patch was suggested by Eric Dumazet.
