> The ipv4_multicast sample application was dropping packets when using 
> mbuf clone. When creating an L2 header and copying metadata from the 
> source packet, the ol_flags were also copied along with all the other 
> metadata. Because the cloned packet had IND_ATTACHED_MBUF flag set in 
> its ol_flags, this caused the packets to never be freed when using 
> rte_pktmbuf_free.
> Since copying ol_flags from the cloned packet is not necessary in the 
> first place, just don't do it.
