From 42ff6af381dff1dfbe1d819afb7639dc1a27bc02 Mon Sep 17 00:00:00 2001 From: Larry Finger Date: Wed, 26 Sep 2012 14:01:31 -0500 Subject: [PATCH] staging: r8712u: Do not queue cloned skb 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.
