doc: improved instructions in p4 test

This directory contains the necessary scripts and configurations to run tests for the P4 functionality of TFS.

## Prerequisites

This test requires some custom monitoring services (latency monitoring and probe).

These services are implemented in Rust and can be found in the `./probe` directory.

To build these services on your target platform, follow the instructions in `./probe/probe-tfs/README.md`.

## Basic scripts

To run the experiments you should use the five scripts in the following order:

# rust-tfs

# Rust-tfs

Client for TFS functionalities written in Rust.

## Dependencies

This project requires the cargo Rust compiler:

```sh

sudo apt-get install protobuf-compiler cargo

```

## Build

Build sources as follows:

```sh

cargo build

```

After a successfuly build, two new executables will be generated in `target/`.
