My impression was that the changes are more likely to be
hardware-specific (like the i40e changes) rather than software-specific,
like changes that might be integrated into the helper.

That said, I can rework for one helper. The way I see it would be the
same code as these patches, as "vxlan_gso_check(struct sk_buff *)" in
drivers/net/vxlan.c which would be called from each driver. Is that what
you had in mind?
