+     "passt implements a thin layer between guest and host, that only
+implements what's strictly needed to pretend processes are running locally.
+The TCP adaptation doesn't keep per-connection packet buffers, and reflects
+observed sending windows and acknowledgements between the two sides.  This TCP
+adaptation is needed as passt runs without the CAP_NET_RAW capability: it
+can't create raw IP sockets on the pod, and therefore needs to map packets at
+Layer-2 to Layer-4 sockets offered by the host kernel.
+
+Also provides pasta, which similarly to slirp4netns, provides networking to
+containers by creating a tap interface available to processes in the
+namespace, and mapping network traffic outside the namespace using native
+Layer-4 sockets.")
