3.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Larry Finger <larry.fin...@lwfinger.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.
