New release specs: Router vs Host configurations

[miri64]

Router and host configurations differ in IPv6 NDP with regards to their behavior. In my opinion this should also be reflected in the release specs. Opinions on that?

Would be great if we can use Wireshark/libpcap dumps for (auto) verification of the behaviour. The idea would be to setup certain scenarios like:

• native <-> native, sniffer on tap-bridge
• SAMR21-XPRO <-> SAMR21-XPRO, sniffer on RasPi or 3rd SAMR21-XPRO
• SAMR21-XPRO <- > RasPi, sniffer on RasPi or 2nd SAMR21-XPRO

and afterwards we have a script that checks the capture-file against a predefined description of a packet flow for IPv6 NDP (RFC 4861 ff) and 6Lo-optimised NDP (RFC 6775). That is, search for RS and matching RA, and NS and NA, do they appear in expected order, interval and have the correct fields and stuff.
