I've given this a test in LXD on my system which triggers the RA stall;
after upgrading it does not wait for an RA before marking the interface
configured and also confirmed that it does not regress the case where
there are existing RA's on the network; those are still received. Note
that we see eth0: Configured before the Discovering IPv6 routers, and
Received Router Advertisement.

Title:
networkd waits 10 seconds for ipv6 network discovery by default
Status in cloud-init package in Ubuntu:
Fix Released
Status in netplan.io package in Ubuntu:
Fix Released
Status in systemd package in Ubuntu:
Fix Committed
Bug description:
[Impact]
* On ipv6 less hosts, boot stalls for 10s
* This is due to implicit RA being on, and wait-online awaiting for RA to
timeout
* Expectation is, that since explicit request for RA was not done, it should
not block network-online.target, whilst all other aspects of
network-online.target should be honored.
[Test Case]
* lxc network set lxdbr0 ipv6.address none
* lxc launch ubuntu-daily:bionic lp1765173
* sleep 20 && lxc exec lp1765173 systemd-analyze blame | head
Bad result is:
12.157s systemd-networkd-wait-online.service
Good result is:
739ms systemd-networkd-wait-online.service
[Regression Potential]
* If explicit IPv6 dhcp/ra was enabled in .network file, the boot
will be blocked awaiting RA response
* Only kernel implicit RA configuration will now become "async"
* This is inline with behaviour of xenial systems
[Other Info]

3. systemd-networkd-wait-online doesn't block for 10 seconds waiting
on an IPV6 Router Advertisement
4. systemd-networkd sends at least two RA solicitation packets waiting
for a response before setting the link to configured. This blocks the
boot for every Ubuntu system where it does not have a IPV6 router
responding to solicitations. THis includes bionic containers, cloud
instances, vms and physical machines.

We can see that we're spending 13 seconds waiting for networkd to say
the network is up.

Here we can see that we start networking at 18:30:51.69, and then IPv6 NDISC
runs for 10 seconds
and then the link is configured at 18:31:05. *AND* we see NDISC stays around
and continues to see if it gets a RA packet.

networkd runs ndisc if your host is configured with ipv6 forwarding
disabled and accept_ra enabled.
% sysctl net.ipv6.conf.all.forwarding
net.ipv6.conf.all.forwarding = 0
% sysctl net.ipv6.conf.all.accept_ra
net.ipv6.conf.all.accept_ra = 1
So ndisc path is expected per systemd code. We should be able to
disable the NDISC link timeout; especially since NDISC stays around to
process RA packets later on anyhow. Nothing is gained by blocking
boot waiting for an RA packet. This is also a change in behavior on
previous LTS, Xenial where the RA handling is done in the kernel
rather than netowkrd.
Full debug output of systemd-networkd during this boot.
