l2tp: test for ethernet header in l2tp_eth_dev_recv()
[ Upstream commit bfc960a8eec023a170a80697fe65157cd4f44f81 ]
close https://bugzilla.kernel.org/show_bug.cgi?id=16529
Before calling dev_forward_skb(), we should make sure skb head contains
at least an ethernet header, even if length included in upper layer said
so. Use pskb_may_pull() to make sure this ethernet header is present in
skb head.
