    Subject[PATCH v4 net-next 0/2] udp: allow forwarding of plain (non-fraglisted) UDP GRO packets
    This series allows to form UDP GRO packets in cases without sockets
    (for forwarding). To not change the current datapath, this is
    performed only when the new corresponding netdev feature is enabled
    via Ethtool (and fraglisted GRO is disabled).
    Prior to this point, only fraglisted UDP GRO was available. Plain UDP
    GRO shows better forwarding performance when a target NIC is capable
    of GSO UDP offload.

    Since v3 [2]:
    - rename introduced netdev feature to reflect that it targets
    forwarding and don't touch fraglisted GRO at all (Willem de Bruijn).

    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.
