Title:
  systemd-networkd silently fails to set vxlan multicast group

Status in systemd:
  Fix Released
Status in systemd package in Ubuntu:
  Fix Released
Status in systemd source package in Focal:
  Fix Released

Bug description:
  [impact]

  setting VXLAN.Group does not correctly configure multicast group

  [test case]

  taken from upstream bug, example networkd config:

  [NetDev]
  Kind=vxlan
  Name=myvx

  [VXLAN]
  VNI=1
  Group=ff02::42:1
  DestinationPort=8472

  After restarting systemd-networkd the VXLAN device is created, but the
  group address is not assigned. Use ip -d link show myvx and networkctl
  show myvx to verify.

  [regression potential]

  any regression would likely cause problems only with VXLAN netdevs
  created by networkd.

  [scope]

  this is needed only for f.

  this was introduced by upstream commit 83cb24ac20b which was first in
  v243, so this bug does not exist in b and earlier.

  this was fixed by upstream commit
  7c9b26900cc33daf080627daf5904de74c1ef267 (and two following commits)
  which were first included in v246, so this is already fixed in g and
  later.

  [original description]

  Fixed upstream, please include [1].

  Thank you.
