Subject: macvlan crash in 3.9

Hello David:

We see macvlan crash in 3.9 because the precise packet length estimation
tries to use the transport header which hasn't been set. This has been
fixed in 3.10 and looks like at least the following commits needs to be
backported to 3.9 stable:

set transport header for untrusted packets:

and the commits that introduces skb_transport_header_was_set():
