C++ definition

Calculates the Duration/ID field for IEEE 802.11 frames to implement the Network(1,2,3,4) Allocation Vector (NAV) mechanism for virtual carrier sensing. This module computes appropriate duration values for different frame types (RTS, data, management) based on IEEE 802.11 standard rules. For RTS frames, it calculates time needed for the complete RTS-CTS-DATA-ACK exchange.
