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.")
