When the dhclient(8) utility is used on an fxp(4) network interface, configuration of the interface could fail with the following warning messages displayed:
fxp0: link state changed to UP
fxp0: link state changed to DOWN
The cause is that the fxp(4) network interface driver resets the controller chip twice upon initialization, and the dhclient(8) utility falsely recognizes the second reset as a link down and attempts reinitialize the interface. As a result, the dhclient(8) utility keeps trying to initialize the interface forever.
