Subject: staging: r8712u: Do not queue cloned skb
From: Larry Finger <[email protected]>
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.
