net/core/tso.c got recent support for USO, and this broke iwlfifi
because the driver implemented a limited form of GSO.

Providing ->gso_type allows for skb_is_gso_tcp() to provide
a correct result.

Johannes, Eric tagged this for net, are you okay with me taking it?
No strong preference here.

I guess that really would normally go through Luca's and Kalle's trees,
