Subject: [ 100/108] l2tp: fix a typo in l2tp_eth_dev_recv()

3.2-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Eric Dumazet <edumazet@...gle.com>

[ Upstream commit c0cc88a7627c333de50b07b7c60b1d49d9d2e6cc ]

While investigating l2tp bug, I hit a bug in eth_type_trans(),
because not enough bytes were pulled in skb head.
