napi_gro_receive is irrelevant. Let aside tunnel, the real work happens
in the protocol specific gro_receive handlers.

However I am an happy retard and I missed that tcp gro stopped depending
on Rx checksum since commit 861b650101eb0c627d171eb18de81dddb93d395e. :o/

So, yes, napi_gro_receive could be used.
