Commit Message

Replies to router solicitation follow a different flow than periodic RA.
This flow currently does not honour the dnssl, rdnss and route_info
options.

This patch modifies the flow to honour those options.

I wanted to send out this patch because the implementation reached
basic functionality and the added tests establish correct expectations.

But the duplication between periodic RA and solicited RA is
too evident at this point to not address it.

In v2 I'll try to create common functions both in code and tests that can
be reused from both periodic and solicited flows for the same options.
