Subject: [PATCH net-next 6/6] veth: use skb_prepare_for_gro()
Date: Wed, 28 Jul 2021 18:24:04 +0200 [thread overview]
Message-ID: <d07db89b5847806e63e2fdf66b88af706a461c9d.1627405778.git.pabeni@redhat.com> (raw)
In-Reply-To: <cover.1627405778.git.pabeni@redhat.com>
Leveraging the previous patch we can now avoid orphaning the
skb in the veth gro path, allowing correct backpressure.
