rte_ipv4_fragment_packet() and rte_ipv6_fragment packet()
call rte_pktmbuf_attach() to attach the segment of the original
packet to the segment of the new fragmented one. Such function
is not declared if RTE_MBUF_REFCNT is disabled, as it needs to
call rte_mbuf_refcnt_update, not declared either.
Therefore, the ipv4/v6 fragmentation libraries are disabled
in that situation.

Mostly a copy-paste of IPv4, with a few caveats.
Only supported packets are those in which fragment extension header is
just after the IPv6 header.
