I have added expert infos to the EIGRP dissector as recommended by Anders
(https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=3907#c2).

There are some test frames in the attached pcap file (eigrp-expertinfo.pcap) to
see the expert infos in action.

1. Invalid key size in AuthTLV, Goodbye Message (Graceful Shutdown)
2. Goodbye Message (Graceful Shutdown)
3. TLV length field set to 0
4. Invalid address length in Sequence TLV. Valid values are 4 (IPv4), 10 (IPX),
16 (IPv6)
5. Invalid prefix length in Internal Route TLV
6. Invalid prefix length in External Route TLV
7. Unknown TLV 0x4242
8. Unreachable destination Internal / External Route TLVs
9. Unreachable destination Internal / External IPv6 Route TLVs
10. Invalid prefix length in Internal IPv6 Route TLV
11. Invalid prefix length in External IPv6 Route TLV

I read the developer and user documentation on expert infos, but just let me
know if the patch needs further changes.

Best Regards,

Jochen
