 Hi
 
 dhcpcd respects the interface carrier status as reported by the kernel, 
 dhclient does not which is why it just works for you.
 -K disables this check (which Joerg suggested).
 
 A superfluous inet address on the interface would not affect dhcpcd 
 carrier checking.
 
 I would recommend running route monitor in a console and / or an 
 ifwatchd script so that you can log if the interface link is really 
 flapping or dhcpcd has a bug here. But I suspect it's either a driver or 
 connectivity issue rather than dhcpcd.
