[dts] [PATCH V1] tests/checksum_offload: Bugfix for bug 529

[Owen Hilyard]

With regards to the failed test cases, that is expected behavior for the
machine I was running it on. The NIC in the dev machine the IOL team is
using is running i40e and the support is P in the compatibility table, and
I'm fairly sure our NIC doesn't support inner checksum offloads but does
support outer checksum offloads. I'll try to remember to increment the
version number if I need more than 1 patch again.

Thanks,
Owen Hilyard
