This reverts commit 5188cd44c55db3e92cd9e77a40b5baa7ed4340f7. Now that GSO layer can track if fragment id has been selected and can allocate on if necessary, we don't need to do this in tap and macvtap. This reverts most of the code and only keeps the new ipv6 fragment id generation function that is still needed. It also solves this issues for packet sockets which were missed before.
