Subject: [PATCH RFC 6/9] veth: use skb_prepare_for_gro()
Date: Wed, 21 Jul 2021 18:44:38 +0200 [thread overview]
Message-ID: <1abe7f6e76864ee634f437972f9249f05414f61c.1626882513.git.pabeni@redhat.com> (raw)
In-Reply-To: <cover.1626882513.git.pabeni@redhat.com>
Leveraging the previous patch we can now avoid orphaning the
skb in the veth gro path, allowing correct backpressure.
Signed-off-by: Paolo Abeni <pabeni@redhat.com>
