+ *		The value of the computed TCP/UDP checksum.  A mode bit
+ *		selects whether this checksum is the full checksum or the
+ *		partial checksum which does not include the pseudo header.
+ *
+ *key_id_octet
+ *		The key ID octet from the IV.  Only valid when first_msdu is
+ *		set.
+ *
+ *classification_filter
+ *		Indicates the number classification filter rule
+ *
+ *ext_wapi_pn_63_48
+ *		Extension PN (packet number) which is only used by WAPI.
+ *		This corresponds to WAPI PN bits [63:48] (pn6 and pn7).  The
+ *		WAPI PN bits [63:0] are in the pn field of the rx_mpdu_start
+ *		descriptor.
+ *
+ *ext_wapi_pn_95_64
+ *		Extension PN (packet number) which is only used by WAPI.

+ *
+ *reported_mpdu_length
+ *		MPDU length before decapsulation.  Only valid when
+ *		first_msdu is set.  This field is taken directly from the
+ *		length field of the A-MPDU delimiter or the preamble length
+ *		field for non-A-MPDU frames.
+ *
+ *first_msdu
+ *		Indicates the first MSDU of A-MSDU.  If both first_msdu and
+ *		last_msdu are set in the MSDU then this is a non-aggregated
+ *		MSDU frame: normal MPDU.  Interior MSDU in an A-MSDU shall
+ *		have both first_mpdu and last_mpdu bits set to 0.
+ *
+ *last_msdu
+ *		Indicates the last MSDU of the A-MSDU.  MPDU end status is
+ *		only valid when last_msdu is set.
+ *
+ *reserved_3a
+ *		Reserved: HW should fill with zero.  FW should ignore.
+ *
+ *pre_delim_err
+ *		Indicates that the first delimiter had a FCS failure.  Only
