/**
 * @ingroup wifi-test
 * @brief Implements a test case to evaluate the reception process of WiFi Physical Layer (PHY)
 * frames (PPDU) with multiple MAC Protocol Data Units (MPDUs).
 *
 * This class extends the TestCase class to simulate and analyze the reception of PPDUs containing
 * either one or two MPDUs. It specifically tests the PHY layer's capability to handle multiple
 * MPDUs addressed to specific receivers, measuring success and failure rates. The simulation setup
 * includes configuring transmit and receive power levels, and the class provides functionality to
 * check statistics related to PPDU and MPDU reception success and failure, as well as overlap
 * handling.

/**
 * @ingroup wifi-test
 * @brief Implements a test case to evaluate the reception process of WiFi Physical Layer (PHY)
 * frames (PPDU) containing multiple MAC Protocol Data Units (MPDUs) in Multi-Link Operation (MLO)
 * contexts.
 *
 * This class extends the TestCase class to simulate and analyze the reception of PPDUs containing
 * either one or two MPDUs in MLO setups. It specifically assesses the WifiPhyRxTraceHelper
 * ability to manage MLO by handling multiple MPDUs addressed to specific receivers across different
 * links, measuring success and failure rates. The simulation setup includes configuring transmit
 * and receive power levels and provides functionality to check statistics related to PPDU and MPDU
 * reception success and failure, as well overlaps and non-overlaps in reception
 * events.
