|
* 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 |

|
* 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. |
