 *		control field is set.  Only set when first_msdu is set.
 *
 *
 * fragment_flag
 *		Fragment indication
 *
 * order
 *		Set if the order bit in the frame control is set.  Only
 *		set when first_msdu is set.
 *
 * u_apsd_trigger
 *		U-APSD trigger frame
 *
 * encrypt_required
 *		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.
 * amsdu_present
 *		AMSDU present
 *
 * mpdu_frame_control_field
 *		Frame control field in header. Only valid when the field is marked valid.
 *
 * mpdu_duration_field
 *		Duration field in header. Only valid when the field is marked valid.
 *
 * mac_addr_adx
 *		MAC addresses in the received frame. Only valid when corresponding
 *		address valid bit is set
 *
 * mpdu_qos_control_field, mpdu_ht_control_field
 *		QoS/HT control fields from header. Valid only when corresponding fields
 *		are marked valid
 *
 * vdev_id
 *		Virtual device associated with this peer
 *		RXOLE uses this to determine intra-BSS routing.
 *
 * service_code
 *		Opaque service code between PPE and Wi-Fi
 *		This field gets passed on by REO to PPE in the EDMA descriptor
 *		('REO_TO_PPE_RING').
 *
 * priority_valid
 *		This field gets passed on by REO to PPE in the EDMA descriptor
 *		('REO_TO_PPE_RING').
 *
 * src_info
 *		Source (virtual) device/interface info. associated with
 *		this peer
 *		This field gets passed on by REO to PPE in the EDMA descriptor
 *		('REO_TO_PPE_RING').
 *
 * multi_link_addr_ad1_ad2_valid
 *		If set, Rx OLE shall convert Address1 and Address2 of received
 *		data frames to multi-link addresses during decapsulation to eth/nwifi
 *
 * multi_link_addr_ad1,ad2
 *		Multi-link receiver address1,2. Only valid when corresponding
 *		valid bit is set
 *
 * authorize_to_send_wds
 *		If not set, RXDMA shall perform error-routing for WDS packets
 *		as the sender is not authorized and might misuse WDS frame
 *		format to inject packets with arbitrary DA/SA.

 *
 * ip_hdr_cksum
 *		This can include the IP header checksum or the pseudo
 *		header checksum used by TCP/UDP checksum.
 *
 * reported_mpdu_length
 *		MPDU length before decapsulation. Only valid when first_msdu is

 *		frames.
 *
 * cce_super_rule
 *		Indicates the super filter rule.
 *
 * cce_classify_not_done_truncate
 *		Classification failed due to truncated frame.
 *
 * cce_classify_not_done_cce_dis
 *		Classification failed due to CCE global disable
 *
 * cumulative_l3_checksum
 *		FISA: IP header checksum including the total MSDU length
 *		that is part of this flow aggregated so far, reported if
 *		'RXOLE_R0_FISA_CTRL. CHKSUM_CUM_IP_LEN_EN' is set
 *
 * rule_indication
 *		Bitmap indicating which of rules have matched.
 *
 * ipv6_options_crc
 *		32 bit CRC computed out of  IP v6 extension headers.
 *
 * da_offset
 *		Offset into MSDU buffer for DA.
 *
 * sa_offset
 *		Offset into MSDU buffer for SA.
 *
 * da_offset_valid
 *		da_offset field is valid. This will be set to 0 in case
 *		of a dynamic A-MSDU when DA is compressed.
 *
 * sa_offset_valid
 *		sa_offset field is valid. This will be set to 0 in case
 *		of a dynamic A-MSDU when SA is compressed.
 *
 * l3_type
 *		The 16-bit type value indicating the type of L3 later
 *		extracted from LLC/SNAP, set to zero if SNAP is not
 *		available.
 *
 * tcp_seq_number
 *		TCP sequence number.
 *
 * tcp_ack_number
 *		TCP acknowledge number.
 *
 * tcp_flag
 *		TCP flags {NS, CWR, ECE, URG, ACK, PSH, RST, SYN, FIN}.
 *
 * lro_eligible
 *		Computed out of TCP and IP fields to indicate that this
 *		MSDU is eligible for LRO.
 *
 * window_size
 *		TCP receive window size.
 *
 * sa_sw_peer_id
 *		sw_peer_id from the address search entry corresponding to the
 *		source address of the MSDU.
 *
 * sa_idx_timeout
 *		Indicates an unsuccessful MAC source address search due to the
 *		expiring of the search timer.
 *
 * da_idx_timeout
 *		Indicates an unsuccessful MAC destination address search due to
 *		the expiring of the search timer.
 *
 * to_ds
 *		Set if the to DS bit is set in the frame control.
 *
 * tid
 *		TID field in the QoS control field
 *
 * sa_is_valid
 *		Indicates that OLE found a valid SA entry.
 *
 * da_is_valid
 *		Indicates that OLE found a valid DA entry.
 *
 * da_is_mcbc
 *		Field Only valid if da_is_valid is set. Indicates the DA address
 *		was a Multicast of Broadcast address.
 *
 * l3_header_padding
 *		Number of bytes padded  to make sure that the L3 header will
 *		always start of a Dword boundary.
 *
 * 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
