/* rx_attention
*
* rxpcu_mpdu_filter_in_category
* Field indicates what the reason was that this mpdu frame
* was allowed to come into the receive path by rxpcu. Values
* are defined in enum %RX_DESC_RXPCU_FILTER_*.
*
* sw_frame_group_id
* SW processes frames based on certain classifications. 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.
*
* first_mpdu
* Indicates the first MSDU of the PPDU. If both first_mpdu
* and last_mpdu are set in the MSDU then this is a not an
* A-MPDU frame but a stand alone MPDU. Interior MPDU in an
* A-MPDU shall have both first_mpdu and last_mpdu bits set to
* 0. The PPDU start status will only be valid when this bit
* is set.
*
* mcast_bcast
* Multicast / broadcast indicator. Only set when the MAC
* address 1 bit 0 is set indicating mcast/bcast and the BSSID
* matches one of the 4 BSSID registers. Only set when
* first_msdu is set.
*
* ast_index_not_found
* Only valid when first_msdu is set. Indicates no AST matching
* entries within the max search count.
*
* ast_index_timeout
* Only valid when first_msdu is set. Indicates an unsuccessful
* search in the address search table due to timeout.
*
* power_mgmt
* Power management bit set in the 802.11 header. Only set
* when first_msdu is set.
*
* non_qos
* Set if packet is not a non-QoS data frame. Only set when
* first_msdu is set.
*
* null_data
* Set if frame type indicates either null data or QoS null
* data format. Only set when first_msdu is set.
*
* mgmt_type
* Set if packet is a management packet. Only set when
* first_msdu is set.
*
* ctrl_type
* Set if packet is a control packet. Only set when first_msdu
* is set.
*
* more_data
* Set if more bit in frame control is set. Only set when
* first_msdu is set.
*
* eosp
* Set if the EOSP (end of service period) bit in the QoS
* control field is set. Only set when first_msdu is set.
*
* a_msdu_error
* Set if number of MSDUs in A-MSDU is above a threshold or if the
* size of the MSDU is invalid. This receive buffer will contain
* all of the remainder of MSDUs in this MPDU w/o decapsulation.
*
* fragment
* Indicates that this is an 802.11 fragment frame. This is
* set when either the more_frag bit is set in the frame
* control or the fragment number is not zero. Only set when
* first_msdu is set.
*
* order
* Set if the order bit in the frame control is set. Only set
* when first_msdu is set.
*
* cce_match
* Indicates that this status has a corresponding MSDU that
* requires FW processing. The OLE will have classification
* ring mask registers which will indicate the ring(s) for
* packets and descriptors which need FW attention.
*
* overflow_err
* PCU Receive FIFO does not have enough space to store the
* full receive packet. Enough space is reserved in the
* receive FIFO for the status is written. This MPDU remaining
* packets in the PPDU will be filtered and no Ack response
* will be transmitted.
*
* msdu_length_err
* Indicates that the MSDU length from the 802.3 encapsulated
* length field extends beyond the MPDU boundary.
*
* tcp_udp_chksum_fail
* Indicates that the computed checksum (tcp_udp_chksum) did
* not match the checksum in the TCP/UDP header.
*
* ip_chksum_fail
* Indicates that the computed checksum did not match the
* checksum in the IP header.
*
* sa_idx_invalid
* Indicates no matching entry was found in the address search
* table for the source MAC address.
*
* da_idx_invalid
* Indicates no matching entry was found in the address search
* table for the destination MAC address.
*
* rx_in_tx_decrypt_byp
* Indicates that RX packet is not decrypted as Crypto is busy
* with TX packet processing.
*
* encrypt_required
* Indicates that this data type frame is not encrypted even if
* the policy for this MPDU requires encryption as indicated in
* the peer table key type.
*
* directed
* MPDU is a directed packet which means that the RA matched
* our STA addresses. 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.
*
* amsdu_parser_error
* A-MSDU could not be properly de-agregated.
*
* sa_idx_timeout
* Indicates an unsuccessful search for the source MAC address
* due to the expiring of the search timer.
*
* da_idx_timeout
* Indicates an unsuccessful search for the destination MAC
* address due to the expiring of the search timer.
*
* msdu_limit_error
* Indicates that the MSDU threshold was exceeded and thus
* all the rest of the MSDUs will not be scattered and will not
* be decasulated but will be DMA'ed in RAW format as a single
* MSDU buffer.
*
* da_is_valid
* Indicates that OLE found a valid DA entry.
*
* da_is_mcbc
* Field Only valid if da_is_valid is set. Indicates the DA address
* was a Multicast or Broadcast address.
*
* sa_is_valid
* Indicates that OLE found a valid SA entry.
*
* 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.

* was allowed to come into the receive path by rxpcu. Values
* are defined in enum %RX_DESC_RXPCU_FILTER_*.
* Note: for ndp frame, if it was expected because the preceding

* used. This setting will also be used for every ndp frame in
* case Promiscuous mode is enabled.

*
* sw_frame_group_id
* SW processes frames based on certain classifications. Values

*
* 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.
