While investigating a kernel panic, our team noticed that UDP traffic
recieved by an STT tunnel will always have a gso_type set as SKB_GSO_UDP.
After decap, we also noticed that traffic that had this flag set had its
fragmentation type set as OVS_FRAG_TYPE_FIRST during key extraction.
When the connection tracker encounters this, it assumes it's already
dealing with fragmented traffic, which might not be the case. This
patch simply ensures we're dealing with an actual fragment before sending
the skb off to be reassembled.

Thanks a lot for the patch.
Greg, have you taken a look at this?
I had it flagged for review but have not yet had a chance to get to it.
I'll do so now.
Thanks,
- Greg
