From: Zongkai LI <zealo...@gmail.com>
This patch updates symbols in logical-fields for ND, such as "nd",
"nd.target", "nd.sll", "nd.tll", to describe more clear about "icmp6.type"
predicate.
And it adds new symbols:
- "nd_rs" stands for Router Solicitation message,
- "nd_ra" stands for Router Advertisement message,
- "nd_rd" stands for Redirect message,
