[Bionic]udev stop notifying when network interface added

Bug Description


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.

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 <email address hidden> "

Could you please collect the udevadm monitor logs, across the openibd restart, both with a previously known working release (e.g. xenial?!) and bionic?

Together with dmesg output, to see what kernel was doing at the same time.
