- New Classes: o ProtocolManager - singleton with which all protocols register o ProtocolCollection - Aggregates all registered protocols; exports methods to work on all protocols o StreamBase - aggregates ProtocolCollection with Stream Core and Control; the client/server side stream classes now derive from StreamBase leading to major reduction in their code (more cleanup pending) - AbstractProtocol now supports the additional methods o createInstance() o protocolFrameSize() o protocolFrameOffset(), protocolFramePayloadSize() o protocolId(), payloadProtocolId() o protocolFrameCksum(), protocolFramePayloadCksum() 0 constructor takes an extra param - frameProtoList - Specific protocols - eth2, llc, snap, ip4, udp, tcp now return length, protocol id and cksums correctly (tcp/udp cksum pending) - StreamConfigDialog - protocol controls for length, cksum and protocolid are automatically updated (not fully working yet)
