frameless_bar
			
			When set, this REO entrance ring struct contains BAR
			info from a multi TID BAR frame. The original multi TID BAR
			frame itself contained all the REO info for the first TID,
			but all the subsequent TID info and their linkage to the REO
			descriptors is passed down as 'frameless' BAR info.
			
			
			
			The only fields valid in this descriptor when this bit
			is set are:
			
			Rx_reo_queue_desc_addr_31_0
			
			RX_reo_queue_desc_addr_39_32
			
			
			
			And within the
			
			Reo_level_mpdu_frame_info:    
			
			   Within Rx_mpdu_desc_info_details:
			
			Mpdu_Sequence_number
			
			BAR_frame
			
			Peer_meta_data
			
			All other fields shall be set to 0
			
			
			
			<legal all>

reserved_5a
			
			<legal 0>

rxdma_push_reason
			
			Indicates why rxdma pushed the frame to this ring
			
			
			
			This field is ignored by REO. 
			
			
			
			<enum 0 rxdma_error_detected> RXDMA detected an error an
			pushed this frame to this queue
			
			<enum 1 rxdma_routing_instruction> RXDMA pushed the
			frame to this queue per received routing instructions. No
			error within RXDMA was detected
			
			<enum 2 rxdma_rx_flush> RXDMA received an RX_FLUSH. As a
			result the MSDU link descriptor might not have the
			last_msdu_in_mpdu_flag set, but instead WBM might just see a
			NULL pointer in the MSDU link descriptor. This is to be
			considered a normal condition for this scenario.
			
			
			
			<legal 0 - 2>

rxdma_error_code
			
			Field only valid when 'rxdma_push_reason' set to
			'rxdma_error_detected'.
			
			
			
			This field is ignored by REO.
			
			
			
			<enum 0 rxdma_overflow_err>MPDU frame is not complete
			due to a FIFO overflow error in RXPCU.
			
			<enum 1 rxdma_mpdu_length_err>MPDU frame is not complete
			due to receiving incomplete MPDU from the PHY
			
			
			<enum 3 rxdma_decrypt_err>CRYPTO reported a decryption
			error or CRYPTO received an encrypted frame, but did not get
			a valid corresponding key id in the peer entry.
			
			<enum 4 rxdma_tkip_mic_err>CRYPTO reported a TKIP MIC
			error
			
			<enum 5 rxdma_unecrypted_err>CRYPTO reported an
			unencrypted frame error when encrypted was expected
			
			<enum 6 rxdma_msdu_len_err>RX OLE reported an MSDU
			length error
			
			<enum 7 rxdma_msdu_limit_err>RX OLE reported that max
			number of MSDUs allowed in an MPDU got exceeded
			
			<enum 8 rxdma_wifi_parse_err>RX OLE reported a parsing
			error
			
			<enum 9 rxdma_amsdu_parse_err>RX OLE reported an A-MSDU
			parsing error
			
			<enum 10 rxdma_sa_timeout_err>RX OLE reported a timeout
			during SA search
			
			<enum 11 rxdma_da_timeout_err>RX OLE reported a timeout
			during DA search
			
			<enum 12 rxdma_flow_timeout_err>RX OLE reported a
			timeout during flow search
			
			<enum 13 rxdma_flush_request>RXDMA received a flush
			request
			
			<enum 14 rxdma_amsdu_fragment_err>Rx PCU reported A-MSDU
			present as well as a fragmented MPDU. A-MSDU defragmentation
			is not supported in Lithium SW so this is treated as an
			error.

mpdu_fragment_number
			
			Field only valid when Reo_level_mpdu_frame_info.
			Rx_mpdu_desc_info_details.Fragment_flag is set.
			
			
			
			The fragment number from the 802.11 header.
			
			
			
			Note that the sequence number is embedded in the field:
			Reo_level_mpdu_frame_info. Rx_mpdu_desc_info_details.
			Mpdu_sequence_number
			
			
			
			<legal all>

sw_exception
			
			When not set, REO is performing all its default MPDU
			processing operations,
			
			When set, this REO entrance descriptor is generated by
			FW, and should be processed as an exception. This implies: 
			
			NO re-order function is needed.
			
			MPDU delinking is determined by the setting of field
			SW_excection_mpdu_delink
			
			Destination ring selection is based on the setting of
			the field SW_exception_destination_ring_valid
			
			In the destination ring descriptor set bit:
			SW_exception_entry
			
			Feature supported only in HastingsPrime
			
			<legal all>

sw_exception_mpdu_delink
			
			Field only valid when SW_exception is set.
			
			1'b0: REO should NOT delink the MPDU, and thus pass this
			MPDU on to the destination ring as is. This implies that in
			the REO_DESTINATION_RING struct field
			Buf_or_link_desc_addr_info should point to an MSDU link
			descriptor
			
			1'b1: REO should perform the normal MPDU delink into
			MSDU operations.
			
			Feature supported only in HastingsPrime
			
			<legal all>

sw_exception_destination_ring_valid
			
			Field only valid when SW_exception is set.
			
			1'b0: REO shall push the MPDU (or delinked MPDU based on
			the setting of SW_exception_mpdu_delink) to the destination
			ring according to field reo_destination_indication.
			
			1'b1: REO shall push the MPDU (or delinked MPDU based on
			the setting of SW_exception_mpdu_delink) to the destination
			ring according to field SW_exception_destination_ring.
			
			Feature supported only in HastingsPrime
			
			<legal all>

sw_exception_destination_ring
			
			Field only valid when fields SW_exception and
			SW_exception_destination_ring_valid are set.
			
			The ID of the ring where REO shall push this frame.
			
			<enum 0 reo_destination_tcl> Reo will push the frame
			into the REO2TCL ring
			
			<enum 1 reo_destination_sw1> Reo will push the frame

phy_ppdu_id
			
			A PPDU counter value that PHY increments for every PPDU

ring_id
			
			Consumer: SW/REO/DEBUG
			
			Producer: SRNG (of RXDMA)
			
			
			
			For debugging. 
			
			This field is filled in by the SRNG module.
			
			It help to identify the ring that is being looked <legal

looping_count
			
			Consumer: SW/REO/DEBUG
			
			Producer: SRNG (of RXDMA)
			
			
			
			For debugging. 
			
			This field is filled in by the SRNG module.
			
			
			
			A count value that indicates the number of times the
			producer of entries into this Ring has looped around the
			ring.
			
			At initialization time, this value is set to 0. On the
			first loop, this value is set to 1. After the max value is
			reached allowed by the number of bits for this field, the
			count value continues with 0 again.
			
			
			
			In case SW is the consumer of the ring entries, it can
			use this field to figure out up to where the producer of
			entries has created new entries. This eliminates the need to
			check where the head pointer' of the ring is located once
			the SW starts processing an interrupt indicating that new
			entries have been put into this ring...
			
			
			
			Also note that SW if it wants only needs to look at the
			LSB bit of this count value.

			check where the head pointer' of the ring is located once
			the SW starts processing an interrupt indicating that new
			entries have been put into this ring...
