| * |
| *key_id_octet |
| * The key ID octet from the IV. Only valid when first_msdu is |

| * |
| *ext_wapi_pn_63_48 |
| * Extension PN (packet number) which is only used by WAPI. |
| * This corresponds to WAPI PN bits [63:48] (pn6 and pn7). The |

| *reported_mpdu_length |
| * MPDU length before decapsulation. Only valid when |
| * first_msdu is set. This field is taken directly from the |
| * length field of the A-MPDU delimiter or the preamble length |
| * field for non-A-MPDU frames. |
| * |
| *first_msdu |
| * Indicates the first MSDU of A-MSDU. If both first_msdu and |
| * last_msdu are set in the MSDU then this is a non-aggregated |
| * MSDU frame: normal MPDU. Interior MSDU in an A-MSDU shall |
| * have both first_mpdu and last_mpdu bits set to 0. |
| * |
| *last_msdu |
| * Indicates the last MSDU of the A-MSDU. MPDU end status is |
| * only valid when last_msdu is set. |
| * |
| *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 decapsulated but will be received in RAW format |
| * as a single MSDU buffer. |
| * |
| *reserved_3a |
| * Reserved: HW should fill with zero. FW should ignore. |

| * tsf_timestamp |
| * Receive TSF timestamp sampled on the rising edge of |
| * rx_clear. For PHY errors this may be the current TSF when |
| * phy_error is asserted if the rx_clear does not assert before |
| * the end of the PHY error. |
| * |
| * wb_timestamp |
| * WLAN/BT timestamp is a 1 usec resolution timestamp which |
| * does not get updated based on receive beacon like TSF. The |
| * same rules for capturing tsf_timestamp are used to capture |
| * the wb_timestamp. |
| * |
| * locationing_timestamp |
| * Timestamp used for locationing. This timestamp is used to |
| * indicate fractions of usec. For example if the MAC clock is |
| * running at 80 MHz, the timestamp will increment every 12.5 |
| * nsec. The value starts at 0 and increments to 79 and |
| * returns to 0 and repeats. This information is valid for |
| * every PPDU. This information can be used in conjunction |
| * with wb_timestamp to capture large delta times. |
| * |
| * phy_err_code |
| * See the 1.10.8.1.2 for the list of the PHY error codes. |
| * |
| * phy_err |
| * Indicates a PHY error was detected for this PPDU. |
| * |
| * rx_location |
| * Indicates that location information was requested. |
| * |
| * txbf_h_info |
| * Indicates that the packet data carries H information which |
| * is used for TxBF debug. |
| * |
| * reserved_18 |
| * Reserved: HW should fill with 0, FW should ignore. |
| * |
| * rx_antenna |
| * Receive antenna value |
| * |
| * tx_ht_vht_ack |
| * Indicates that a HT or VHT Ack/BA frame was transmitted in |
| * response to this receive packet. |
| * |
| * bb_captured_channel |
| * Indicates that the BB has captured a channel dump. FW can |
| * then read the channel dump memory. This may indicate that |
| * the channel was captured either based on PCU setting the |
| * capture_channel bit BB descriptor or FW setting the |
| * capture_channel mode bit. |
| * |
| * reserved_19 |
| * Reserved: HW should fill with 0, FW should ignore. |
| * |
| * bb_length |
| * Indicates the number of bytes of baseband information for |
| * PPDUs where the BB descriptor preamble type is 0x80 to 0xFF |
| * which indicates that this is not a normal PPDU but rather |
| * contains baseband debug information. |
| * |
| * reserved_20 |
| * Reserved: HW should fill with 0, FW should ignore. |
| * |
| * ppdu_done |
| * PPDU end status is only valid when ppdu_done bit is set. |
| * Every time HW sets this bit in memory FW/SW must clear this |
| * bit in memory. FW will initialize all the ppdu_done dword |
| * to 0. |
