 |  *		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 |

 |  *		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. |
