Alexei reported a performance regression on vxlan, caused by commit 3347c9602955 "ipv4: gso: make inet_gso_segment() stackable"
GSO vxlan packets were not properly segmented, adding IP fragments while they were not expected.
Rename 'bool tunnel' to 'bool encap', and add a new boolean to express the fact that UDP should be fragmented. This fragmentation is triggered by skb->encapsulation being set.
Remove a "skb->encapsulation = 1" added in above commit, as its not needed, as frags inherit skb->frag from original GSO skb.
