Title:
  [Bionic]udev stop notifying when network interface added

Status in systemd package in Ubuntu:
  New

Bug description:
  Expected:

  After a network driver restart, the network interfaces are deleted and
  added again, the udev should notify that new interface was added. then
  the interface service should be started accordingly.

  Actual:
  Udev doesn't notify about that new interface is added and the interface service doesn't start.

  More details:

  We see this issue when using Mellanox OFED package.
  Mellanox OFED add a service per network device and add udev rule to start this service when the interface added.
  After driver restart ("/etc/init.d/openibd restart") the network devices doesn't loaded, since udev doesn't notify.

  The system should run from udev rules, since once the driver creates
  an interface, there should be a udev event saying a new interface is
  added, then this script will be ran by udev (the OS).

  " /bin/systemctl --no-block start mlnx_interface_mgr at ib0.service "
