2.6.27.59-stable review patch. If anyone has any objections, please let us know.
------------------ From: David S. Miller <[email protected]> commit 4e085e76cbe558b79b54cbab772f61185879bc64 upstream. Unconditional use of skb->dev won't work here, try to fetch the econet device via skb_dst()->dev instead. Suggested by Eric Dumazet.
