Description
I am currently using a custom script to try out MAC pinning on a single port.
For this I have to modify the FDB of the switch.
But - every time the link gets down, the fdb table for this interface is flushed.
There is no hotplugd event when the interface gets back up again, so I have to manually run the script - or write another script for a periodic check.
That's where I found out that there is no hotplugd event for this case.

Research direction
Start in interface-event.c around the referenced event-handling code and trace how link changes become hotplugd events. Add the IFEV_LINK_UP event for an interface returning to the up state, then verify that a hotplug script can receive it after the link recovers.
