Crate consomme

The Consomme user-mode TCP stack.

This crate implements a user-mode TCP stack designed for use with virtualization. The guest operating system sends Ethernet frames, and this crate parses them and distributes the data streams to individual TCP and UDP sockets.

The current implementation supports OS-backed TCP and UDP sockets, essentially causing this stack to act as a NAT implementation, providing guest OS networking by leveraging the host’s network stack.

This implementation includes a small DHCP server for address assignment.
