...UFO, select a new fragment id. When we store the fragment id into skb_shinfo, set the bit in the skb so we can re-use the selected id. This preserves the behavior of UFO packets generated on the host and solves the issue of id generation for packet sockets and tap/macvtap devices. This patch moves ipv6_select_ident() back in to the header file. It also provides the helper function that sets skb_shinfo() frag id and sets the bit. It also makes sure that we select the fragment id when doing just gso validation, since it's possible for the packet to come from an untrusted source (VM) and be forwarded thro...

...lisions 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.

The issue was that IPv6 UFO/GSO implementation expects the fragment id to be supplied in
