C++ definition

Implements the single protection mechanism for IEEE 802.11 networks as defined in the standard section 8.2.5.2. This module calculates the Duration/ID field values for different frame types (RTS, CTS, BlockAckReq, BlockAck, data, management) to properly set the Network(1,2,3,4) Allocation Vector (NAV) in receiving stations.
