			Cookie field exclusively used by SW. 
			
			
			In case of 'NULL' pointer, this field is set to 0
			
			
			HW ignores the contents, accept that it passes the
			programmed value on to other descriptors together with the
			physical address 
			
			
			Field can be used by SW to for example associate the
			buffers physical address with the virtual address
			
			The bit definitions as used by SW are within SW HLD
			specification
			
			
			NOTE:
			
			The three most significant bits can have a special
			meaning in case this struct is embedded in a TX_MPDU_DETAILS
			STRUCT, and field transmit_bw_restriction is set
			
			
			In case of NON punctured transmission:
			
			Sw_buffer_cookie[20:19] = 2'b00: 20 MHz TX only
