netplan breaks Xen VIF driver

switching this bug over to netplan, as there are already several nic drivers blacklisted from the "replugging" in netplan, due to them not supporting (or breaking) unbinding/rebinding.

This bug was fixed in the package nplan - 0.32

---------------
nplan (0.32) bionic; urgency=medium

  * src/nm.c: better handle the UUID generation; the order of iterating
    through interaces may affect things here. Also make sure the tests catch
    a null UUID.

The verification of the Stable Release Update for nplan has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regressions.

I just tested this with a 20171220 daily build of 17.10 in us-east-1, in a custom VPC, and it appears to be working fine.

This bug was fixed in the package nplan - 0.32~16.04.3

---------------
nplan (0.32~16.04.3) xenial; urgency=medium

  * tests/integration.py: Really fix skipping test_routes_v6 for the NM
    backend.

nplan (0.32~16.04.2) xenial; urgency=medium

  * tests/integration.py: Fix test_routes_v6 that I clobbered when I re-applied
    the skip rules for 16.04 after merging in 0.32.

nplan (0.32~16.04.1) xenial; urgency=medium

  * Backport netplan 0.32 to 16.04. (LP: #1713142)
  * debian/control: Depend on systemd (>= 229-4ubuntu20) for the PrimarySlave
    feature backported in that revision.
  * tests/integration.py: Skip tests that are still not yet supported in xenial

nplan (0.32) bionic; urgency=medium

  * src/nm.c: better handle the UUID generation; the order of iterating
    through interaces may affect things here. Also make sure the tests catch
    a null UUID.

nplan (0.31) bionic; urgency=medium

  [ Mathieu Trudel-Lapierre ]
  * src/nm.c: generate a UUID for a connection only as needed; when we're
    dealing with NM VLANs. (LP: #1712921)
  * debian/tests/autostart: Make the autostart test more verbose and avoid
    failing right from the start when systemd-networkd is disabled.
    (LP: #1699371)
  * tests/integration.py: bump the NetworkManager timeout for settling to
    120 seconds, autopkgtest infrastructure tends to be a little slow for the
    network device configuration to be applied and noticed by NM.
    (LP: #1699371)

  [ Dimitri John Ledkov ]
  * Reload udevd to invalidate configuration cache of .rules/.link files
    as generate step may have changed them. LP: #1669564

  [ Dan Streetman ]
  * Add another interface driver exception to netplan replug to prevent unbind
    of the Xen VIF interfaces. (LP: #1729573)

nplan (0.30) artful; urgency=medium

  * Add an "optional" syntax node for now to all devices. This is unimplemented
    for now, but intended to allow users to mark some devices as optional: to
    make sure they do not delay boot when configured. (LP: #1664844)

nplan (0.29) artful; urgency=medium

  * Fix autopkgtests in a world where /run/NetworkManager/conf.d already
    exists. nplan is enabled by default, so it might well have the directory
    already created on the filesystem.

nplan (0.28) artful; urgency=medium

  * Revert 56cd3eec which disabled IPv6 Router Advertisements by default. It
    broke default network config in LXD and was contrary to the defaults used
    by the kernel. Reopens LP: 1655440. (LP: #1717404)
  * Add "accept-ra:" key for all device types; this will default to OFF but
    allow users to disable processing Router Advertisements when required by
    their network setup. (LP: #1655440)

nplan (0.27) artful; urgency=medium

  [ Mathieu Trudel-Lapierre ]
  * Fix crash in systemd generator if called by an user on the command-line
  * coverage: fix exclusions to properly not cover our "never reached defaults"

  [ Dimitri John Ledkov ]
  * tests/integration.py: In teardown, stop systemd-networkd.socket.
  * src/networkd.c: Set UseMTU=true by default, whenever DHCP is in use.
    (LP: #1717471)
  * tests/integration.py: fix resolved detection.

  * tests/integration.py: bump the NetworkManager timeout for settling to
    120 seconds, autopkgtest infrastructure tends to be a little slow for the
    network device configuration to be applied and noticed by NM.
    (LP: #1699371)

  * Reload udevd to invalidate configuration cache of .rules/.link files
    as generate step may have changed them. LP: #1669564

  [ Dan Streetman ]
  * Add another interface driver exception to netplan replug to prevent unbind
    of the Xen VIF interfaces. (LP: #1729573)

  * Add an "optional" syntax node for now to all devices. This is unimplemented
    for now, but intended to allow users to mark some devices as optional: to
    make sure they do not delay boot when configured. (LP: #1664844)

  * Fix autopkgtests in a world where /run/NetworkManager/conf.d already
    exists. nplan is enabled by default, so it might well have the directory
    already created on the filesystem.

  * Revert 56cd3eec which disabled IPv6 Router Advertisements by default. It
    broke default network config in LXD and was contrary to the defaults used
    by the kernel. Reopens LP: 1655440. (LP: #1717404)
  * Add "accept-ra:" key for all device types; this will default to OFF but
    allow users to disable processing Router Advertisements when required by
    their network setup. (LP: #1655440)

  * Fix crash in systemd generator if called by an user on the command-line
  * coverage: fix exclusions to properly not cover our "never reached defaults"

  [ Dimitri John Ledkov ]
  * tests/integration.py: In teardown, stop systemd-networkd.socket.
  * src/networkd.c: Set UseMTU=true by default, whenever DHCP is in use.
    (LP: #1717471)
  * tests/integration.py: fix resolved detection.

  * Bonding:
    - Add support for specifying a primary slave. (LP: #1709135)
  * Rebind:
    - Fix brcmfmac harder. Treat any 'brcmfmac' driver as not supporting
      rebind. (LP: #1712224)
  * Autopkgtests:
    - Add allow-stderr. Systemd now bleats about a the networkd socket still
      being around and enabled when we restart the service; but we don't need
      to care since we're /restarting/ the service to load the new config.
    - Fix the autostart package to be more sensible: we don't really care if
