Subject: [PATCH net] iwlwifi: provide gso_type to GSO packets
Date: Mon, 25 Jan 2021 07:09:49 -0800 [thread overview]
Message-ID: <20210125150949.619309-1-eric.dumazet@gmail.com> (raw)
From: Eric Dumazet <edumazet@google.com>
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")
