C++ definition

Implements rate selection for IEEE 802.11 QoS frames. Selects appropriate transmission rates for different frame types (data, management, control, response) based on configured parameters and dynamic conditions. Supports different bitrates for multicast frames, response frames (ACK, CTS, BlockAck), and can use a rate control module for dynamic rate adaptation.
