| |
From: Eric Dumazet <edumazet@google.com>
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.
