[dpdk-stable] [PATCH v2] example/ipv4_multicast: fix app hanging when using clone

[Thomas Monjalon]

> > 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.
