Victor Julien 8fa5a2c025 Split applayer and raw stream reassembly
Split stream reassembly in 2 parts: a part that sends ack'd data to the app

data into larger chunks for raw inspection.

Victor Julien 301522f316 Add TCP_GET_WSCALE macro for easy access to wscale. Update StreamTcp to use it. Default to wscale 14 (max) in case of midstream as there seems to be no reliable way to predict wscale if we missed it. 16 years ago

Victor Julien b102ea2123 Big update:

- Simplify application level protocol in the Tcp Session.
- Add some debugging memory counters.
