To: pve-devel
Allows to drop most upstream patches, expect one for IPv6 SLAAC support
due to being stale/unmerged as of 3.9.0.
Adds a simple patch dropping a line from setup.py, as it tries to
install a non-existing file and would thus otherwise fail the install
step.

Our ifupdown2 upstream mirror [0] must also be updated accordingly, of
course. The updated/referenced commit for the submodule points to the
`3.9.0` upstream tag.

-Subject: [PATCH] scheduler: avoid waiting for stdout eof of /etc/network/
- scripts
-
-Scripts in /etc/network/ are executed using `exec_command` which
-captures stdout by default, and thus waits for stdout end-of-file via
-`Popen.communicate()`. However, this can cause hangs if the network
-script executes a long-running command in the background. Can be
-reproduced by putting the following (executable) script in
-/etc/network/if-up.d/:
-
- #!/bin/sh
- sleep 5&
-
-This script will cause `ifreload -a` to wait for 5 seconds per network
-interface.
-
-To avoid waiting, do not capture stdout when executing /etc/network/
-scripts. This also improves compatibility with ifupdown, which runs
-the above script in the background.

This patch makes it possible to use an IPv6 address for the local VXLAN
tunnel address.

Stefan suggested the inclusion of this patch, as it's been a fairly
requested features.
Split it off completely from the other changes and marked it as RFC tho,
as upstream still doesn't seem to have decided if the attribute should
be renamed to `vxlan-local-tunnelip6`. Pulling it in now would mean that
we're "stuck" with that name, if we don't want to break users later on,
if the attribute is really renamed.
(Or we could support both styles in that case.)

+This commit adds the option to pass an IPv6 address instead of an IPv4 address to use as
