Note that sub field Buffer_type shall be set to Receive_REO_queue_descriptor receive_queue_number Indicates the MPDU queue ID to which this MPDU link descriptor belongs Used for tracking and debugging reserved_1b vld Valid bit indicating a session is established and the queue descriptor is valid(Filled by SW) associated_link_descriptor_counter Indicates which of the 3 link descriptor counters shall be incremented or decremented when link descriptors are added or removed from this flow queue. MSDU link descriptors related with MPDUs stored in the re-order buffer shall also be included in this count. disable_duplicate_detection When set, do not perform any duplicate detection. soft_reorder_enable When set, REO has been instructed to not perform the actual re-ordering of frames for this queue, but just to insert the reorder opcodes. Note that this implies that REO is also not going to perform any MSDU level operations, and the entire MPDU (and thus pointer to the MSDU link descriptor) will be pushed to a destination ring that SW has programmed in a SW programmable configuration register in REO ac Indicates which access category the queue descriptor belongs to(filled by SW) bar Indicates if BAR has been received (mostly used for debug purpose and this is filled by REO) rty Retry bit is checked if this bit is set. chk_2k_mode Indicates what type of operation is expected from Reo when the received frame SN falls within the 2K window See REO MLD document for programming details. oor_mode Out of Order mode: Indicates what type of operation is expected when the received frame falls within the OOR window. See REO MLD document for programming details. ba_window_size Indicates the negotiated (window size + 1). it can go up to Max of 256bits. A value 255 means 256 bitmap, 63 means 64 bitmap, 0 (means non-BA session, with window size of 0). The 3 values here are the main values validated, but other values should work as well. A BA window size of 0 (=> one frame entry bitmat), means that there is NO RX_REO_QUEUE_EXT descriptor following this RX_REO_QUEUE STRUCT in memory A BA window size of 1 - 105, means that there is 1 RX_REO_QUEUE_EXT descriptor directly following this RX_REO_QUEUE STRUCT in memory. A BA window size of 106 - 210, means that there are 2 RX_REO_QUEUE_EXT descriptors directly following this RX_REO_QUEUE STRUCT in memory A BA window size of 211 - 256, means that there are 3 RX_REO_QUEUE_EXT descriptors directly following this RX_REO_QUEUE STRUCT in memory pn_check_needed When set, REO shall perform the PN increment check pn_shall_be_even Field only valid when 'pn_check_needed' is set. When set, REO shall confirm that the received PN number is not only incremented, but also always an even number pn_shall_be_uneven Field only valid when 'pn_check_needed' is set. When set, REO shall confirm that the received PN number is not only incremented, but also always an uneven number pn_handling_enable Field only valid when 'pn_check_needed' is set. When set, and REO detected a PN error, HW shall set the 'pn_error_detected_flag'. pn_size Size of the PN field check. Needed for wrap around handling... ignore_ampdu_flag When set, REO shall ignore the ampdu_flag on the entrance descriptor for this queue. reserved_2b svld Sequence number in next field is valid one. It can be filled by SW if the want to fill in the any negotiated SSN, otherwise REO will fill the sequence number of first received packet and set this bit to 1. ssn Starting Sequence number of the session, this changes whenever window moves. (can be filled by SW then maintained by REO) current_index Points to last forwarded packet seq_2k_error_detected_flag Set by REO, can only be cleared by SW When set, REO has detected a 2k error jump in the sequence number and from that moment forward, all new frames are forwarded directly to FW, without duplicate detect, reordering, etc. pn_error_detected_flag Set by REO, can only be cleared by SW When set, REO has detected a PN error and from that moment forward, all new frames are forwarded directly to FW, without duplicate detect, reordering, etc. reserved_3a pn_valid PN number in next fields are valid. It can be filled by SW if it wants to fill in the any negotiated SSN, otherwise REO will fill the pn based on the first received packet and set this bit to 1. pn_31_0 pn_63_32 Bits [63:32] of the PN number. pn_95_64 Bits [95:64] of the PN number. pn_127_96 Bits [127:96] of the PN number. last_rx_enqueue_timestamp This timestamp is updated when an MPDU is received and accesses this Queue Descriptor. It does not include the access due to Command TLVs or Aging (which will be updated in Last_rx_dequeue_timestamp). last_rx_dequeue_timestamp This timestamp is used for Aging. When an MPDU or multiple MPDUs are forwarded, either due to window movement, bar, aging or command flush, this timestamp is updated. Also when the bitmap is all zero and the first time an MPDU is queued (opcode=QCUR), this timestamp is updated for aging. ptr_to_next_aging_queue_31_0 Address (address bits 31-0)of next RX_REO_QUEUE descriptor in the 'receive timestamp' ordered list. From it the Position of this queue descriptor in the per AC aging waitlist can be derived. Value 0x0 indicates the 'NULL' pointer which implies that this is the last entry in the list. ptr_to_next_aging_queue_39_32 Address (address bits 39-32)of next RX_REO_QUEUE descriptor in the 'receive timestamp' ordered list. From it the Position of this queue descriptor in the per AC aging waitlist can be derived. Value 0x0 indicates the 'NULL' pointer which implies that this is the last entry in the list. reserved_11a ptr_to_previous_aging_queue_31_0 Address (address bits 31-0)of next RX_REO_QUEUE descriptor in the 'receive timestamp' ordered list. From it the Position of this queue descriptor in the per AC aging waitlist can be derived. Value 0x0 indicates the 'NULL' pointer which implies that this is the first entry in the list. ptr_to_previous_aging_queue_39_32 Address (address bits 39-32)of next RX_REO_QUEUE descriptor in the 'receive timestamp' ordered list. From it the Position of this queue descriptor in the per AC aging waitlist can be derived. Value 0x0 indicates the 'NULL' pointer which implies that this is the first entry in the list. reserved_13a rx_bitmap_31_0 When a bit is set, the corresponding frame is currently held in the re-order queue.

Forwarding reason is Timeout The counter saturates and freezes at 0x3F forward_due_to_bar_count The number of times that REO started forwarding frames even though there is a hole in the bitmap. Forwarding reason is reception of BAR frame. The counter saturates and freezes at 0x3F duplicate_count The number of duplicate frames that have been detected frames_in_order_count The number of frames that have been received in order (without a hole that prevented them from being forwarded immediately) This corresponds to the Reorder opcodes: 'FWDCUR' and 'FWD BUF' bar_received_count The number of times a BAR frame is received. This corresponds to the Reorder opcodes with 'DROP' The counter saturates and freezes at 0xFF mpdu_frames_processed_count The total number of MPDU frames that have been processed by REO. 'Processing' here means that REO has received them out of the entrance ring, and retrieved the corresponding RX_REO_QUEUE Descriptor. Note that this count includes duplicates, frames that later had errors, etc. Note that field 'Duplicate_count' indicates how many of these MPDUs were duplicates. msdu_frames_processed_count The total number of MSDU frames that have been processed by REO. 'Processing' here means that REO has received them out of the entrance ring, and retrieved the corresponding RX_REO_QUEUE Descriptor. Note that this count includes duplicates, frames that later had errors, etc. total_processed_byte_count An approximation of the number of bytes processed for this queue. 'Processing' here means that REO has received them out of the entrance ring, and retrieved the corresponding RX_REO_QUEUE Descriptor. Note that this count includes duplicates, frames that later had errors, etc. In 64 byte units late_receive_mpdu_count The number of MPDUs received after the window had already moved on. The 'late' sequence window is defined as (Window SSN - 256) - (Window SSN - 1) This corresponds with Out of order detection in duplicate detect FSM The counter saturates and freezes at 0xFFF window_jump_2k The number of times the window moved more then 2K The counter saturates and freezes at 0xF (Note: field name can not start with number: previous 2k_window_jump) hole_count The number of times a hole was created in the receive bitmap.
