What is the appropriate way to extract the ip src/dst address from a packet?

I see two options: enabling the metadata and somehow hooking into that
(it looks possible, but there isn't much information about the
metadata system and PacketMetadata/PacketMetadata::ItemIterator
classes).

The other option that seems available is to serialize the packet and
then try to deserialize the header.

Ipv4Header iph;
iph.Deserialize(packet->Serialize().Begin());
	
But it always fails: assert failed.
