Documentation

Overview

Package ipv4 contains the implementation of the ipv4 network protocol. To use it in the networking stack, this package must be added to the project, and activated on the stack by passing ipv4.NewProtocol() as one of the network protocols when calling stack.New(). Then endpoints can be created by passing ipv4.ProtocolNumber as the network protocol number when calling Stack.NewEndpoint().
