is there an easy way to register a callback function or block until a link
status change of an Ethernet device occurs in the libbsd stack?
Searching for it, I found some references for EV_NETDEV in kqueue, but this
seems to be a legacy function which has been removed years ago.
I solved this with setting an hook function for the dhcpcd and react to
the "reason" string in the environment.
Link is "CARRIER" and NOCARRIER".
Look at dhcpcd01 test.
