In proxySTA it means that the TA matched * an entry in our address search table with the corresponding * 'no_ack' bit is the address search entry cleared. * * buffer_fragment * Indicates that at least one of the rx buffers has been * fragmented. If set the FW should look at the rx_frag_info * descriptor described below. * * mpdu_length_err * Indicates that the MPDU was pre-maturely terminated * resulting in a truncated MPDU. Don't trust the MPDU length * field. * * tkip_mic_err * Indicates that the MPDU Michael integrity check failed * * decrypt_err * Indicates that the MPDU decrypt integrity check failed * * fcs_err * Indicates that the MPDU FCS check failed * * flow_idx_timeout * Indicates an unsuccessful flow search due to the expiring of * the search timer. * * flow_idx_invalid * flow id is not valid. * * decrypt_status_code * Field provides insight into the decryption performed. Values * are defined in enum %RX_DESC_DECRYPT_STATUS_CODE_*. * * rx_bitmap_not_updated * Frame is received, but RXPCU could not update the receive bitmap * due to (temporary) fifo constraints. * * msdu_done * If set indicates that the RX packet data, RX header data, RX * PPDU start descriptor, RX MPDU start/end descriptor, RX MSDU * start/end descriptors and RX Attention descriptor are all * valid. This bit must be in the last octet of the * descriptor. * */ struct hal_rx_desc_qcn9274_compact { struct rx_msdu_end_qcn9274_compact msdu_end; struct rx_mpdu_start_qcn9274_compact mpdu_start; u8 msdu_payload[]; } __packed; #define RX_BE_PADDING0_BYTES 8 #define RX_BE_PADDING1_BYTES 8 #define HAL_RX_BE_PKT_HDR_TLV_LEN 112 struct rx_pkt_hdr_tlv { __le64 tag; __le64 phy_ppdu_id; u8 rx_pkt_hdr[HAL_RX_BE_PKT_HDR_TLV_LEN]; }; struct hal_rx_desc_wcn7850 { __le64 msdu_end_tag; struct rx_msdu_end_qcn9274 msdu_end; u8 rx_padding0[RX_BE_PADDING0_BYTES]; __le64 mpdu_start_tag; struct rx_mpdu_start_qcn9274 mpdu_start; struct rx_pkt_hdr_tlv pkt_hdr_tlv; u8 msdu_payload[]; }; struct rx_pkt_hdr_tlv_qcc2072 { __le32 tag; __le64 phy_ppdu_id; u8 rx_pkt_hdr[HAL_RX_BE_PKT_HDR_TLV_LEN]; }; struct hal_rx_desc_qcc2072 { __le32 msdu_end_tag; struct rx_msdu_end_qcn9274 msdu_end; u8 rx_padding0[RX_BE_PADDING0_BYTES]; __le32 mpdu_start_tag; struct rx_mpdu_start_qcn9274 mpdu_start; struct rx_pkt_hdr_tlv_qcc2072 pkt_hdr_tlv; u8 msdu_payload[]; }; struct hal_rx_desc { union { struct hal_rx_desc_qcn9274_compact qcn9274_compact; struct hal_rx_desc_wcn7850 wcn7850; struct hal_rx_desc_qcc2072 qcc2072; } u; } __packed; #endif /* ATH12K_RX_DESC_H */
