rfc2765_3.1_payloadlength.seq - Verify IPv6 <-> IPv4 header
translation in accordance with RFC2765 [SIIT]
Router
Before this test starts, run initialize.seq.
This test verifies that NUT can translates IPv4 header
to IPv6 header, when IPv4 header contain options.

<===================
ICMPv6 Echo Request
IPv6 Header
src address : TN LINK1 IPv4 embedded IPv6 address
dst address : TN LINK0 IPv4 embedded IPv6 address
ICMPv6 echo request

<< PASS >>
TN (Link0) receive four ICMPv6 echo requests,
with correct payload length.
<< FAIL >>
TN (Link0) receive four ICMPv6 echo requests,
with payload length 8 bytes too large.

3.1. Translating IPv4 Headers into IPv6 Headers
Payload Length:
Total length value from IPv4 header, minus the size
of the IPv4 header and IPv4 options, if present.
