[roll] Roll fuchsia [netstack3] Generate stable SLAAC addrs with opaque IIDs
Use opaque IIDs to generate stable SLAAC addresses (both global and
link-local) when enabled, as described in RFC 7217, ensuring that
generated IIDs do not conflict with any IIDs reserved by IANA or already
assigned to the stack.
Add a global stack configuration option to control whether IIDs are
derived deterministically from the link-layer address or generated with
the stable secret key by default. (This global default can be overridden
for specific interfaces.) Enable opaque IIDs by default, and create a
new variant of Netstack3 for conformance tests that disables them to get
deterministic SLAAC addresses.
After this change the stack does not yet perform address regeneration on
DAD failure for stable addresses; that will come later.

This repository contains Fuchsia's Global Integration manifest files.
All changes should be made to the internal version of this repository. Our infrastructure automatically updates this version when the internal one changes.
Currently all changes must be made by a Google employee. Non-Google employees wishing to make a change can ask for assistance in one of the communication channels documented at get involved.
First install Jiri.
Next run:
$ jiri init $ jiri import minimal https://fuchsia.googlesource.com/integration $ jiri update
Third party projects should have their own subdirectory in ./third_party.
