Statistics->IPv[4|6] Statistics -> Source and Destination Addresses incorrect for tunneling

Summary

Source and destination addresses are pulled from net_src/net_dst packet_info fields.

pinfo_stats_tree.c:

	/* update source branch */
	tick_stat_node(st, st_str_src, 0, FALSE);
	tick_stat_node(st, address_to_str(pinfo->pool, &pinfo->net_src), st_node_src, FALSE);
	/* update destination branch */
	tick_stat_node(st, st_str_dst, 0, FALSE);
	tick_stat_node(st, address_to_str(pinfo->pool, &pinfo->net_dst), st_node_dst, FALSE);

The Multi IP layer problem:

That is because Wireshark will always display the Source/Destination address pair of the highest layer it can find,

The result is that the statistics display a mix and IPv4 and IPv6 addresses where there is tunneling of mixed versions.
(Hmmm - even if versions aren't mixed, the addresses are incorrect if the tunneled address is being returned)

(packet-ip.c and packet-ipv6.c - last one in wins)

Statistics->IPv6 Statistics -> Source and Destination Addresses

What is the current bug behavior?

(Determining unique source/destination IP addresses separately.)

What is the expected correct behavior?

Display lowest (outer) layer IP addresses.
