This patch assumes that the fm10k hardware will ignore existing IPv4/v6 header fields for length and checksum as well as the length and checksum fields for outer UDP headers. I have no means of testing this as I do not have any mlx5 hardware but thought I would submit it as an RFC to see if anyone out there wants to test this and see if this does in fact enable this functionality allowing us to to segment UDP tunneled frames that have an outer checksum.
