If you referring to "send packet to a directly connected target (on
ethernet) that has no entry in the ARP cache" - that's standard behaviour,
and always have been.

Router sees packet, sends ARP probe, drops packet.   Eventually, ARP
reply comes in, ARP cache is populated, next packet is directly sent.

It was that way long before CEF ever came around - and the only way to
avoid this is "more buffering, more complex switching paths, more bugs".
