Values * are defined in enum %RX_DESC_SW_FRAME_GRP_ID_*. * * phy_ppdu_id * A ppdu counter value that PHY increments for every PPDU * received. The counter value wraps around. * * unsup_ktype_short_frame * This bit will be '1' when WEP or TKIP or WAPI key type is * received for 11ah short frame. Crypto will bypass the received * packet without decryption to RxOLE after setting this bit. * * rx_in_tx_decrypt_byp * Indicates that RX packet is not decrypted as Crypto is * busy with TX packet processing. * * overflow_err * RXPCU Receive FIFO ran out of space to receive the full MPDU. * Therefore this MPDU is terminated early and is thus corrupted. * * This MPDU will not be ACKed. * * RXPCU might still be able to correctly receive the following * MPDUs in the PPDU if enough fifo space became available in time. * * mpdu_length_err * Set by RXPCU if the expected MPDU length does not correspond * with the actually received number of bytes in the MPDU. * * tkip_mic_err * Set by Rx crypto when crypto detected a TKIP MIC error for * this MPDU. * * decrypt_err * Set by RX CRYPTO when CRYPTO detected a decrypt error for this * MPDU or CRYPTO received an encrypted frame, but did not get a * valid corresponding key id in the peer entry. * * unencrypted_frame_err * Set by RX CRYPTO when CRYPTO detected an unencrypted frame while * in the peer entry field 'All_frames_shall_be_encrypted' is set. * * pn_fields_contain_valid_info * Set by RX CRYPTO to indicate that there is a valid PN field * present in this MPDU. * * fcs_err * Set by RXPCU when there is an FCS error detected for this MPDU. * * msdu_length_err * Set by RXOLE when there is an msdu length error detected * in at least 1 of the MSDUs embedded within the MPDU. * * rxdma0_destination_ring * rxdma1_destination_ring * The ring to which RXDMA0/1 shall push the frame, assuming * no MPDU level errors are detected. In case of MPDU level * errors, RXDMA0/1 might change the RXDMA0/1 destination. Values * are defined in %enum RX_MPDU_END_RXDMA_DEST_RING_*. * * 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. */ /* Padding bytes to avoid TLV's spanning across 128 byte boundary */ #define HAL_RX_DESC_PADDING0_BYTES 4 #define HAL_RX_DESC_PADDING1_BYTES 16 #define HAL_RX_DESC_HDR_STATUS_LEN 120 struct hal_rx_desc_ipq8074 { __le32 msdu_end_tag; struct rx_msdu_end_ipq8074 msdu_end; __le32 rx_attn_tag; struct rx_attention attention; __le32 msdu_start_tag; struct rx_msdu_start_ipq8074 msdu_start; u8 rx_padding0[HAL_RX_DESC_PADDING0_BYTES]; __le32 mpdu_start_tag; struct rx_mpdu_start_ipq8074 mpdu_start; __le32 mpdu_end_tag; struct rx_mpdu_end mpdu_end; u8 rx_padding1[HAL_RX_DESC_PADDING1_BYTES]; __le32 hdr_status_tag; __le32 phy_ppdu_id; u8 hdr_status[HAL_RX_DESC_HDR_STATUS_LEN]; u8 msdu_payload[]; } __packed; struct hal_rx_desc_qcn9074 { __le32 msdu_end_tag; struct rx_msdu_end_qcn9074 msdu_end; __le32 rx_attn_tag; struct rx_attention attention; __le32 msdu_start_tag; struct rx_msdu_start_qcn9074 msdu_start; u8 rx_padding0[HAL_RX_DESC_PADDING0_BYTES]; __le32 mpdu_start_tag; struct rx_mpdu_start_qcn9074 mpdu_start; __le32 mpdu_end_tag; struct rx_mpdu_end mpdu_end; u8 rx_padding1[HAL_RX_DESC_PADDING1_BYTES]; __le32 hdr_status_tag; __le32 phy_ppdu_id; u8 hdr_status[HAL_RX_DESC_HDR_STATUS_LEN]; u8 msdu_payload[]; } __packed; struct hal_rx_desc_wcn6855 { __le32 msdu_end_tag; struct rx_msdu_end_wcn6855 msdu_end; __le32 rx_attn_tag; struct rx_attention attention; __le32 msdu_start_tag; struct rx_msdu_start_wcn6855 msdu_start; u8 rx_padding0[HAL_RX_DESC_PADDING0_BYTES]; __le32 mpdu_start_tag; struct rx_mpdu_start_wcn6855 mpdu_start; __le32 mpdu_end_tag; struct rx_mpdu_end mpdu_end; u8 rx_padding1[HAL_RX_DESC_PADDING1_BYTES]; __le32 hdr_status_tag; __le32 phy_ppdu_id; u8 hdr_status[HAL_RX_DESC_HDR_STATUS_LEN]; u8 msdu_payload[]; } __packed; struct hal_rx_desc { union { struct hal_rx_desc_ipq8074 ipq8074; struct hal_rx_desc_qcn9074 qcn9074; struct hal_rx_desc_wcn6855 wcn6855; } u; } __packed; #define HAL_RX_RU_ALLOC_TYPE_MAX 6 #define RU_26 1 #define RU_52 2 #define RU_106 4 #define RU_242 9 #define RU_484 18 #define RU_996 37 #endif /* ATH11K_RX_DESC_H */
