struct buffer_addr_info released_buff_or_desc_addr_info

			Consumer: WBM/SW/FW

			Producer: SW/TQM/RXDMA/REO/SWITCH



			Details of the physical address of the buffer or link
			descriptor that is being released. Note that within this
			descriptor, WBM will look at the 'owner' of the released
			buffer/descriptor and forward it to SW/FW is WBM is not the
			owner.



			In case of TQM releasing Tx MSDU link descriptors with
			Tqm_release_reason set to 'tqm_fw_reason3,' HastingsPrime
			WBM can optionally release the MSDU buffers pointed to by
			the MSDU link descriptors to FW and override the
			tx_rate_stats field, for FW reinjection of these MSDUs
			(FR54309). This is not supported in Pine.

release_source_module

			Indicates which module initiated the release of this
			buffer or descriptor



			<enum 0 release_source_TQM> TQM released this buffer or
			descriptor

			<enum 1 release_source_RXDMA> RXDMA released this buffer
			or descriptor

			<enum 2 release_source_REO> REO released this buffer or
			descriptor

			<enum 3 release_source_FW> FW released this buffer or
			descriptor

			<enum 4 release_source_SW> SW released this buffer or
			descriptor

			<legal 0-4>

bm_action

			Consumer: WBM/SW/FW

			Producer: SW/TQM/RXDMA/REO/SWITCH



			Field only valid when the field return_buffer_manager in
			the Released_buff_or_desc_addr_info indicates:

			WBM_IDLE_BUF_LIST or

			WBM_IDLE_DESC_LIST



			An MSDU extension descriptor shall never be marked as



			<enum 0 Put_in_idle_list> Put the buffer or descriptor
			back in the idle list. In case of MSDU or MDPU link
			descriptor, BM does not need to check to release any
			individual MSDU buffers



			<enum 1 release_msdu_list > This BM action can only be
			used in combination with buffer_or_desc_type being
			msdu_link_descriptor. Field first_msdu_index points out
			which MSDU pointer in the MSDU link descriptor is the first
			of an MPDU that is released.

			BM shall release all the MSDU buffers linked to this
			first MSDU buffer pointer. All related MSDU buffer pointer
			entries shall be set to value 0, which represents the 'NULL
			pointer. When all MSDU buffer pointers in the MSDU link
			descriptor are 'NULL', the MSDU link descriptor itself shall
			also be released.



			<enum 2 Put_in_idle_list_expanded> CURRENTLY NOT
			IMPLEMENTED....

			Put the buffer or descriptor back in the idle list. Only
			valid in combination with buffer_or_desc_type indicating
			MDPU_link_descriptor.

			BM shall release the MPDU link descriptor as well as all
			MSDUs that are linked to the MPDUs in this descriptor.



			<legal 0-2>

buffer_or_desc_type

			Consumer: WBM/SW/FW

			Producer: SW/TQM/RXDMA/REO/SWITCH



			Field only valid when WBM is marked as the
			return_buffer_manager in the Released_Buffer_address_info



			Indicates that type of buffer or descriptor is being
			released



			<enum 0 MSDU_rel_buffer> The address points to an MSDU
			buffer

			<enum 1 msdu_link_descriptor> The address points to an
			TX MSDU link descriptor

			<enum 2 mpdu_link_descriptor> The address points to an
			MPDU link descriptor

			<enum 3 msdu_ext_descriptor > The address points to an
			MSDU extension descriptor.

			In case BM finds this one in a release ring, it passes
			it on to FW...

			<enum 4 queue_ext_descriptor> The address points to an
			TQM queue extension descriptor. WBM should treat this is the
			same way as a link descriptor. That is, put the 128 byte
			buffer back in the link buffer idle list.



			<legal 0-4>

first_msdu_index

			Consumer: WBM/SW/FW

			Producer: SW/TQM/RXDMA/REO/SWITCH



			Field only valid for the bm_action release_msdu_list.



			The index of the first MSDU in an MSDU link descriptor
			all belonging to the same MPDU.



			<legal 0-6>

			Consumer: WBM/SW/FW

			Producer: TQM



			Field only valid when Release_source_module is set to
			release_source_TQM



			(rr = Release Reason)

			<enum 0 tqm_rr_frame_acked> frame is removed because an
			ACK of BA for it was received

			<enum 1 tqm_rr_rem_cmd_rem> frame is removed because a
			remove command of type Remove_mpdus initiated by SW

			<enum 2 tqm_rr_rem_cmd_tx> frame is removed because a
			remove command of type Remove_transmitted_mpdus initiated by
			SW

			<enum 3 tqm_rr_rem_cmd_notx> frame is removed because a
			remove command of type Remove_untransmitted_mpdus initiated
			by SW

			<enum 4 tqm_rr_rem_cmd_aged> frame is removed because a
			remove command of type Remove_aged_mpdus or
			Remove_aged_msdus initiated by SW

			<enum 5 tqm_fw_reason1> frame is removed because a
			remove command where fw indicated that remove reason is
			fw_reason1

			<enum 6 tqm_fw_reason2> frame is removed because a
			remove command where fw indicated that remove reason is
			fw_reason1

			<enum 7 tqm_fw_reason3> frame is removed because a
			remove command where fw indicated that remove reason is
			fw_reason1

			<enum 8 tqm_rr_rem_cmd_disable_queue> frame is removed
			because a remove command of type
			remove_mpdus_and_disable_queue or
			remove_msdus_and_disable_flow initiated by SW



			<legal 0-8>



			In case of TQM releasing Tx MSDU link descriptors with
			Tqm_release_reason set to 'tqm_fw_reason3,' HastingsPrime
			WBM can optionally release the MSDU buffers pointed to by
			the MSDU link descriptors to FW and override the
			tx_rate_stats field, for FW reinjection of these MSDUs
			(FR54309). This is not supported in Pine.

rxdma_push_reason

			<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>



			In case of RXDMA releasing Rx MSDU link descriptors,'
			Maple/Spruce WBM can optionally override the tx_rate_stats
			field with Rx_msdu_desc_info_details (FR59859). This is not
			supported in HastingsPrime, Pine or Moselle.

rxdma_error_code

			Field only valid when 'rxdma_push_reason' set to
			'rxdma_error_detected'.



			<enum 0 rxdma_overflow_err>MPDU frame is not complete
			due to a FIFO overflow error in RXPCU.

			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.

			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.

reo_push_reason

			Field only valid when Release_source_module is set to
			release_source_REO



			Indicates why REO pushed the frame to this release ring



			<enum 0 reo_error_detected> Reo detected an error an
			pushed this frame to this queue

			<enum 1 reo_routing_instruction> Reo pushed the frame to
			this queue per received routing instructions. No error

looping_count

			Consumer: WBM/SW/FW

			Producer: SW/TQM/RXDMA/REO/SWITCH



			A count value that indicates the number of times the
			producer of entries into the Buffer Manager 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.
