    ipv6: Select fragment id during UFO segmentation if not set. · 0508c07f
    Vlad Yasevich authored
    If the IPv6 fragment id has not been set and we perform
    fragmentation due to UFO, select a new fragment id.
    We now consider a fragment id of 0 as unset and if id selection
    process returns 0 (after all the pertrubations), we set it to
    0x80000000, thus giving us ample space not to create collisions
    with the next packet we may have to fragment.
    When doing UFO integrity checking, we also select the
    fragment id if it has not be set yet.   This is stored into
    the skb_shinfo() thus allowing UFO to function correclty.
    This patch also removes duplicate fragment id generation code
    and moves ipv6_select_ident() into the header as it may be
    used during GSO.
