translate UDP source/destination port number appropriately which is involved in ICMPv6 payload.
We can not re-calculate ICMP checksum because translator does not re-assemble this fragmented packet so we can not get an ICMP length information.
- Natpt_logTSlot() is called at the time when tSlot entry was created or removed.
it caused PMTUD problem on netbsd (we need to check esp4_ctlinput).
(it caused PMTUD problem on netbsd - we should revisit esp4_ctlinput)

If the original pointer points after the IPv4 or IPv6 header, translated pointer points at position which has same offset from the end of IPv4 or IPv6 header.

…rom received HoT/CoT packet.
-- RFC2529 2. Maximum Transmission Unit The default MTU size for IPv6 packets on an IPv4 domain is 1480 octets. This size may be varied by a Router Advertisement [DISC] containing an MTU option which specifies a different MTU, or by manual configuration of each node.
