164 * the policy for this MPDU requires encryption as indicated in
165 * the peer table key type.
166 *
167 * directed
168 * MPDU is a directed packet which means that the RA matched
169 * our STA addresses. In proxySTA it means that the TA matched

1229 * tsf_timestamp
1230 * Receive TSF timestamp sampled on the rising edge of

1232 * phy_error is asserted if the rx_clear does not assert before
1233 * the end of the PHY error.
1234 *
1235 * wb_timestamp
1236 * WLAN/BT timestamp is a 1 usec resolution timestamp which
1237 * does not get updated based on receive beacon like TSF. The
1238 * same rules for capturing tsf_timestamp are used to capture
1239 * the wb_timestamp.
1240 *
1241 * locationing_timestamp
1242 * Timestamp used for locationing. This timestamp is used to
1243 * indicate fractions of usec. For example if the MAC clock is
1244 * running at 80 MHz, the timestamp will increment every 12.5
1245 * nsec. The value starts at 0 and increments to 79 and
1246 * returns to 0 and repeats. This information is valid for
1247 * every PPDU. This information can be used in conjunction
1248 * with wb_timestamp to capture large delta times.
1249 *
1250 * phy_err_code
1251 * See the 1.10.8.1.2 for the list of the PHY error codes.
1252 *
1253 * phy_err
1254 * Indicates a PHY error was detected for this PPDU.
1255 *
1256 * rx_location
1257 * Indicates that location information was requested.
1258 *
1259 * txbf_h_info
1260 * Indicates that the packet data carries H information which
1261 * is used for TxBF debug.
1262 *
1263 * reserved_18
1264 * Reserved: HW should fill with 0, FW should ignore.
1265 *
1266 * rx_antenna
1267 * Receive antenna value
1268 *
1269 * tx_ht_vht_ack
1270 * Indicates that a HT or VHT Ack/BA frame was transmitted in
1271 * response to this receive packet.
1272 *
1273 * bb_captured_channel
1274 * Indicates that the BB has captured a channel dump. FW can
1275 * then read the channel dump memory. This may indicate that
1276 * the channel was captured either based on PCU setting the
1277 * capture_channel bit BB descriptor or FW setting the
1278 * capture_channel mode bit.
1279 *
1280 * reserved_19
1281 * Reserved: HW should fill with 0, FW should ignore.
1282 *
1283 * bb_length
1284 * Indicates the number of bytes of baseband information for
1285 * PPDUs where the BB descriptor preamble type is 0x80 to 0xFF
1286 * which indicates that this is not a normal PPDU but rather
1287 * contains baseband debug information.
1288 *
1289 * reserved_20
1290 * Reserved: HW should fill with 0, FW should ignore.
1291 *
1292 * ppdu_done
1293 * PPDU end status is only valid when ppdu_done bit is set.
1294 * Every time HW sets this bit in memory FW/SW must clear this
1295 * bit in memory. FW will initialize all the ppdu_done dword
1296 * to 0.
