Detailed Description

Debug modules.

This namespace collects several modules helpful for PPI debugging. The modules allow to manually pass packets into a network and read back the output packets.

There are three categories of modules:

• Active modules (ActiveSource, ActiveSink) are triggered by external calls. Calling submit() / request() will send the request into the module network synchronously. From this it follows, that senf::ppi::run() should not be called. Instead senf::ppi::init() is used to initialize the network and explicit calls to the active debug modules drive the execution.
• Passive modules (PassiveSource, PassiveSink) contain a queue to save packets (either packets to be transmitted or packets received) and are driven by the network.
• Feeder (almost-)modules (ActiveFeederSource, ActiveFeederSink) are a hybrid of both types of modules: They contain a packet queue but actively drive the network and are used together with senf::ppi::run(). senf::ppi::run() will automatically terminate if all available packets have been processed. These are not modules, they are collections combining a passive debug module and a senf::ppi::ActiveFeeder.
