Title:
  networkd does not complete interface configuration if Link MTUBytes is
  set

Status in systemd:
  Fix Released
Status in systemd package in Ubuntu:
  Fix Released
Status in systemd source package in Bionic:
  In Progress

Bug description:
  [impact]

  interfaces configured with .network file [Link] section specifying
  MTUBytes will not be successfully brought up.

  [test case]

  configure interface e.g.

  Name=ens3

  [Network]
  DHCP=ipv4
  LinkLocalAddressing=ipv6

  [Link]
  MTUBytes=1550

  start/restart networkd, the interface will never reach 'routable'
  stage and will not get an IPv4 address.

  [regression potential]

  regressions will likely occur during networkd
  configuration/startup/restart, and would likely cause failure to
  successfully setup the interface.

  [other info]

  this is a regression-proposed caused by incomplete backport for bug
  1850704
