    net: original ingress device index in PKTINFO · 0b922b7a
    David Ahern 提交于
    Applications such as OSPF and BFD need the original ingress device not
    the VRF device; the latter can be derived from the former. To that end
    add the skb_iif to inet_skb_parm and set it in ipv4 code after clearing
    the skb control buffer similar to IPv6. From there the pktinfo can just
    pull it from cb with the PKTINFO_SKB_CB cast.
    
    The previous patch moving the skb->dev change to L3 means nothing else
    is needed for IPv6; it just works.
