The Dingo project is a collection of work that needs to be done to clean up and advance the network stack. The overriding goal is to remove duplicated functionality while also adding new features that will make FreeBSD easier to use both for the network engineer and experimenter and for the first time user.
The Dingo project is closely related to the Netperf Project which is removing all the Giant locks from the various network stacks.
