first_msdu_in_mpdu_flag

			<enum 1 first_msdu> This MSDU is the first one in the

			Parsed from RX_MSDU_END TLV . In the case MSDU spans
			over multiple buffers, this field will be valid in the Last
			buffer used by the MSDU
			
			
			
			<enum 0 Not_last_msdu> There are more MSDUs linked to
			this MSDU that belongs to this MPDU 
			
			<enum 1 Last_msdu> this MSDU is the last one in the
			MPDU. This setting is only allowed in combination with
			'Msdu_continuation' set to 0. This implies that when an msdu
			is spread out over multiple buffers and thus
			msdu_continuation is set, only for the very last buffer of
			the msdu, can the 'last_msdu_in_mpdu_flag' be set.
			
			
			
			When both first_msdu_in_mpdu_flag and
			last_msdu_in_mpdu_flag are set, the MPDU that this MSDU
			belongs to only contains a single MSDU.

msdu_continuation

			Full MSDU length in bytes after decapsulation. 
			
			
			
			This field is still valid for MPDU frames without
			A-MSDU.  It still represents MSDU length after decapsulation
			
			
			
			Or in case of RAW MPDUs, it indicates the length of the

reo_destination_indication
			
			Parsed from RX_MSDU_END TLV . In the case MSDU spans
