Description: Returns the length of the payload, including the medium access control (MAC) header. This value is expressed in bytes. If you set the NIWLANA_DSSS_DEMOD_HEADER_DETECTION_ENABLED attribute to NIWLANA_VAL_TRUE, the toolkit extracts the payload length from the demodulated LENGTH field of the frame. The LENGTH field is defined in sections 15.2.3.5, 18.2.3.5, 18.2.3.12, and 19.3.2.1.2 of IEEE Standard 802.11-2007.

If you set the NIWLANA_DSSS_DEMOD_HEADER_DETECTION_ENABLED attribute to NIWLANA_VAL_FALSE, the value you specify in the NIWLANA_DSSS_PAYLOAD_LENGTH attribute specifies the payload length. The toolkit returns a value of -1 if it encounters various data lengths during the averaging process.
