Kevin Krakauer e1b21f3c8c Use PacketBuffers, rather than VectorisedViews, in netstack. ... PacketBuffers are analogous to Linux's sk_buff. They hold all information about a packet, headers, and payload. This is important for: * iptables to access various headers of packets * Preventing the clutter of passing different net and link headers along with VectorisedViews to packet handling functions. This change only affects the incoming packet path, and a future change will change the outgoing path.
