  Log Message:
  datapath: compat: keep skb mark across tunnel devices.

Older kernel skb_scrub_packet() has bug which resets skb mark for
all packet. It is fixed during 3.18 release where it is reset
only for packets crossing namespace. So OVS is forced to use
compat skb_scrub_packet() on older kernel.
This is related to upstream bug fix commit ca7c7b9059e3
("skbuff: Do not scrub skb mark within the same name space").
