This commit adds a new TCP/IP service to MINIX 3. As its core, the service uses the lwIP TCP/IP stack for maintenance reasons. The service aims to be compatible with NetBSD userland, including its low-level network management utilities. It also aims to support modern features such as IPv6. In summary, the new LWIP service has support for the following main features: - TCP, UDP, RAW sockets with mostly standard BSD API semantics; - IPv6 support: host mode (complete) and router mode (partial); - most of the standard BSD API socket options (SO_); - all of the standard BSD API message flags (MSG_); - the most used protocol-specific socket and control options; - a default loopback interface and the ability to create one more; - configuration-free ethernet interfaces and driver tracking; - queuing and multiple concurrent requests to each ethernet driver; - standard ioctl(2)-based BSD interface management; - radix tree backed, destination-based routing; - routing sockets for standard BSD route reporting and management; - multicast traffic and multicast group membership tracking; - Berkeley Packet Filter (BPF) devices; - standard and custom sysctl(7) nodes for many internals; - a slab allocation based, hybrid static/dynamic memory pool model. Many of its modules come with fairly elaborate comments that cover many aspects of what is going on. The service is primarily a socket driver built on top of the libsockdriver library, but for BPF devices it is at the same time also a character driver.
