    net: introduce skb_transport_header_was_set() · fda55eca
    Eric Dumazet authored
    We have skb_mac_header_was_set() helper to tell if mac_header
    was set on a skb. We would like the same for transport_header.
    
    __netif_receive_skb() doesn't reset the transport header if already
    set by GRO layer.
    
    Note that network stacks usually reset the transport header anyway,
    after pulling the network header, so this change only allows
    a followup patch to have more precise qdisc pkt_len computation
    for GSO packets at ingress side.
