struct rx_mpdu_details reo_level_mpdu_frame_info

			Consumer: SW

			Producer: RXDMA



			Details related to the MPDU being pushed to SW, valid
			only if end_of_ppdu is set to 0

struct buffer_addr_info status_buff_addr_info

			Consumer: SW

			Producer: RXDMA



			Details of the physical address of the first status
			buffer used for the PPDU (either the PPDU that included the
			MPDU being pushed to SW if end_of_ppdu = 0, or the PPDU
			whose end is indicated through end_of_ppdu = 1)

rxdma_push_reason

			Indicates why RXDMA pushed the frame to this ring



			<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 is set to
			'rxdma_error_detected.'



			<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 and
			end_of_ppdu is set to 0.



			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>

frameless_bar

			When set, this SW monitor 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 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>

status_buf_count

			A count of status buffers used so far for the PPDU
			(either the PPDU that included the MPDU being pushed to SW
			if end_of_ppdu = 0, or the PPDU whose end is indicated
			through end_of_ppdu = 1)

end_of_ppdu

			Pine RXDMA can be configured to generate a separate
			'SW_MONITOR_RING' descriptor at the end of a PPDU (either
			through an 'RX_PPDU_END' TLV or through an 'RX_FLUSH') to
			demarcate PPDUs.



			For such a descriptor, this bit is set to 1 and fields
			Reo_level_mpdu_frame_info, mpdu_fragment_number and
			Frameless_bar are all set to 0.



			Otherwise this bit is set to 0.

reserved_6a

			<legal 0>

phy_ppdu_id

			A PPDU counter value that PHY increments for every PPDU
			received

			The counter value wraps around. Pine RXDMA can be
			configured to copy this from the RX_PPDU_START TLV for every
			output descriptor.



			<legal all>

reserved_7a

			<legal 0>

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
			all>

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.
