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 will include the driver patches as a seperate RFC following this series.
