bmv2

Executes packet-processing logic from P4 programs via JSON files, enabling rapid testing and iteration without recompiling the core switch, as highlighted by the workflow with p4c.

Includes targets like simple_switch and psa_switch to accommodate different P4 architectures, facilitating development across various switch models as described in the targets directory.

Provides a CLI for table population, an event logger for packet tracing, and a debugger for step-by-step execution, essential for debugging P4 logic, with tools like runtime_CLI.py and p4dbg.py.

Allows loading shared libraries at runtime on supported systems via --load-modules, enabling extensibility without modifying core code, though it depends on dlopen availability.
