+ * dest_chip_id
+ * If intra_bss is set, copied by RXOLE from 'ADDR_SEARCH_ENTRY'

+ * Set if IPv4/v6 packet is using IPsec AH
+ *
+ * l4_offset
+ * Depending upon mode bit, this field either indicates the

+ * Indicates that this data type frame is not encrypted even if
+ * 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
+ * an entry in our address search table with the corresponding
+ * 'no_ack' bit is the address search entry cleared.
+ *
+ * buffer_fragment
+ * Indicates that at least one of the rx buffers has been
+ * fragmented. If set the FW should look at the rx_frag_info
+ * descriptor described below.

+ * are defined in enum %RX_DESC_DECRYPT_STATUS_CODE_*.
+ *
+ * rx_bitmap_not_updated

+ * due to (temporary) fifo constraints.
+ *
+ * msdu_done
+ * If set indicates that the RX packet data, RX header data, RX
+ * PPDU start descriptor, RX MPDU start/end descriptor, RX MSDU
