commit 0fb101be97ca27850c5ecdbd1269423ce4d1f607 upstream.
UDP tunnel packets can't be GRO in-between their endpoints as this causes different issues. The UDP GRO fwd vxlan tests were relying on this and their expectations have to be fixed.
We keep both vxlan tests and expected no GRO from happening. The vxlan UDP GRO bench test was removed as it's not providing any valuable information now.
