- 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
