|
|
|
* 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.
