[Intel-wired-lan] [next PATCH S26 04/12] i40e: do TSO only if CHECKSUM_PARTIAL is set

[Deepthi Kavalur]

From: Shannon Nelson <shannon.nelson at intel.com>

Don't bother trying to set up a TSO if the skb->ip_summed is not
set to CHECKSUM_PARTIAL.

Testing-Hints:
I'm sure there's a better test available, but I found this by
inspection and then adding a debug printk to see what was happening.
For now, just verify that the code is inserted and compiles.
