From: Eric Dumazet <[email protected]>
commit 81a86e1bd8e7060ebba1718b284d54f1238e9bf9 upstream.
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.
Fixes: 3d5b459ba0e3 ("net: tso: add UDP segmentation support")
