+
+In `spp_classifier_mac_do()`, it receives packets from rx port and send them

+
+On the other hand, `spp_forward` is for 1:1 or N:1 (called as merge)
+forwarding defined in `spp_forward.c`.
+Source and destination ports are decided from `core_info`
+and given to `set_use_interface()` in which first argment is
+destination info and second one is source.

+  ```c
+  /* spp_forward.c */

+	}
+  ```
 
+### L2 Multicast Support
 
-### Packet Cloning
+Multicast for resolving ARP requests is also supported in SPP_VF.
+It is implemented as `handle_l2multicast_packet()` and called from
+`classify_packet()` for incoming multicast packets.
 
+  ```c
+  /* classify_packet() in classifier_mac.c */
+
+  /* L2 multicast(include broadcast) ? */
+  if (unlikely(is_multicast_ether_addr(&eth->d_addr))) {
+	RTE_LOG(DEBUG, SPP_CLASSIFIER_MAC,
+			"multicast mac address.\n");
+	handle_l2multicast_packet(rx_pkts[i],
+			classifier_info, classified_data);
+	continue;
+  }
+  ```
+
+For distributing multicast packet, it is cloned with
+`rte_mbuf_refcnt_update()`.
 
+  ```c
+  /* classifier_mac.c */
+
+  /* handle L2 multicast(include broadcast) packet */
+  static inline void
+  handle_l2multicast_packet(struct rte_mbuf *pkt,
+		struct classifier_mac_info *classifier_info,
+		struct classified_data *classified_data)
+  {
+	int i;
+
+	if (unlikely(classifier_info->num_active_classified == 0)) {
+		RTE_LOG(ERR, SPP_CLASSIFIER_MAC, "No mac address.(l2multicast packet)\n");
+		rte_pktmbuf_free(pkt);
+		return;
+	}
+
+	rte_mbuf_refcnt_update(pkt, classifier_info->num_active_classified);
+
+	for (i= 0; i < classifier_info->num_active_classified; i++) {
+		push_packet(pkt, classified_data +
+			(long)classifier_info->active_classifieds[i]);
+	}
