GSO: Provide software checksum of tunneled UDP fragmentation offload On reviewing the code I realized that GRE and UDP tunnels could cause a kernel panic if we used GSO to segment a large UDP frame that was sent through the tunnel with an outer checksum and hardware offloads were not available. In order to correct this we need to update the feature flags that are passed to the skb_segment function so that in the event of UDP fragmentation being requested for the inner header the segmentation function will correctly generate the checksum for the payload if we cannot segment the outer header.
