Subject: [PATCH net-next 0/2] udp: allow forwarding of plain (non-fraglisted) UDP GRO packets
Date: Mon, 18 Jan 2021 19:31:55 +0000 [thread overview]
Message-ID: <20210118193122.87271-1-alobakin@pm.me> (raw)
This series allows to form UDP GRO packets in cases without sockets,
primarily for forwarding. To not change the current datapath, this
is performed only when the new netdev feature is enabled via Ethtool.
Prior to this point, only fraglisted UDP GRO was available.
Since v2 [1]:
- convert to a series;
- new: add new netdev_feature to explicitly enable/disable UDP GRO
when there is no socket, defaults to off (Paolo Abeni).
Since v1 [0]:
- drop redundant 'if (sk)' check (Alexander Duyck);
- add a ref in the commit message to one more commit that was
an important step for UDP GRO forwarding.
