    net: vrf: Flip IPv6 output path from FIB lookup hook to out hook · 4c1feac5
    David Ahern authored
    Flip the IPv6 output path to use the l3mdev tx out hook. The VRF dst
    is not returned on the first FIB lookup. Instead, the dst on the
    skb is switched at the beginning of the IPv6 output processing to
    send the packet to the VRF driver on xmit.
    
    Link scope addresses (linklocal and multicast) need special handling:
    specifically the oif the flow struct can not be changed because we
    want the lookup tied to the enslaved interface. ie., the source address
    and the returned route MUST point to the interface scope passed in.
    Convert the existing vrf_get_rt6_dst to handle only link scope addresses.
