There are two cases where the AP may receive hotplug event for an existing interface, without first getting a hot-unplug request for it. - bootrom loading the firmware image and booting into that, which only generates a hotplug event. i.e. no hot-unplug event, as the module never went away. - Or the firmware on the module crashed and sent hotplug request again to the SVC, which got propagated to AP. Handle such cases by first removing the interface, with a clear print message shown to the user. And then following the normal hotplug sequence to add the interface.
