Add event handler. Events notify us about things like when a
disassociation frame has arrived. Nice side effect; As we acknowledge the event reason after receiving a disassociation frame (which happens pretty often by wi(4) hostap) now, the FW issues an automatic reassociation, and we do not loose network connectivity anymore.
