    SubjectGSO with udp_tunnel_xmit_skb
    From
    Hi folks,

    When sending arbitrary SKBs with udp_tunnel_xmit_skb, the networking
    stack does not appear to be utilizing UFO on the outgoing UDP packets,
    which significantly caps the transmission speed. I see about 50% CPU
    usage in this send path, triggered for every single outgoing packet.
    Is there a particular skb option I need to set to enable this? I read
    Tom's patch [1] from last year, but this seems to be about setting the
    inner packet type. In my case, the inner type is opaque encrypted
    data, so there's not a relevant setting.

    Thanks,
    Jason
