This patch set addresses a number of issues I found while sorting out enabling UDP GSO Segmentation support for ixgbe/ixgbevf. Specifically there were a number of issues related to the checksum and such that seemed to cause either minor irregularities or kernel panics in the case of the offload request being allowed to traverse between name spaces.
With this set applied I am was able to get UDP GSO traffic to pass over vxlan tunnels in both offloaded modes and non-offloaded modes for ixgbe and ixgbevf. I submitted the driver specific patches earlier as an RFC: https://patchwork.ozlabs.org/project/netdev/list/?series=42477&archive=both&state=* v2: Updated patches based on feedback from Eric Dumazet Split first patch into several patches based on feedback from Eric v3: Drop patch that was calling pskb_may_pull as it was redundant.
