/* rx_attention
 *
 * rxpcu_mpdu_filter_in_category
 *		Field indicates what the reason was that this mpdu frame
 *		was allowed to come into the receive path by rxpcu. Values
 *		are defined in enum %RX_DESC_RXPCU_FILTER_*.
 *
 * sw_frame_group_id
 *		SW processes frames based on certain classifications. Values
 *		are defined in enum %RX_DESC_SW_FRAME_GRP_ID_*.
 *
 * phy_ppdu_id
 *		A ppdu counter value that PHY increments for every PPDU
 *		received. The counter value wraps around.
 *
 * first_mpdu
 *		Indicates the first MSDU of the PPDU.  If both first_mpdu
 *		and last_mpdu are set in the MSDU then this is a not an
 *		A-MPDU frame but a stand alone MPDU.  Interior MPDU in an
 *		A-MPDU shall have both first_mpdu and last_mpdu bits set to
 *		0.  The PPDU start status will only be valid when this bit
 *		is set.
 *
 * mcast_bcast
 *		Multicast / broadcast indicator.  Only set when the MAC
 *		address 1 bit 0 is set indicating mcast/bcast and the BSSID
 *		matches one of the 4 BSSID registers. Only set when
 *		first_msdu is set.
 *
 * ast_index_not_found
 *		Only valid when first_msdu is set. Indicates no AST matching
 *		entries within the max search count.
 *
 * ast_index_timeout
 *		Only valid when first_msdu is set. Indicates an unsuccessful
 *		search in the address search table due to timeout.
 *
 * power_mgmt
 *		Power management bit set in the 802.11 header.  Only set
 *		when first_msdu is set.
 *
 * non_qos
 *		Set if packet is not a non-QoS data frame.  Only set when
 *		first_msdu is set.
 *
 * null_data
 *		Set if frame type indicates either null data or QoS null
 *		data format.  Only set when first_msdu is set.
 *
 * mgmt_type
 *		Set if packet is a management packet.  Only set when
 *		first_msdu is set.
 *
 * ctrl_type
 *		Set if packet is a control packet.  Only set when first_msdu
 *		is set.
 *
 * more_data
 *		Set if more bit in frame control is set.  Only set when
 *		first_msdu is set.
 *
 * eosp
 *		Set if the EOSP (end of service period) bit in the QoS
 *		control field is set.  Only set when first_msdu is set.
 *
 * a_msdu_error
 *		Set if number of MSDUs in A-MSDU is above a threshold or if the
 *		size of the MSDU is invalid. This receive buffer will contain
 *		all of the remainder of MSDUs in this MPDU w/o decapsulation.
 *
 * fragment
 *		Indicates that this is an 802.11 fragment frame.  This is
 *		set when either the more_frag bit is set in the frame
 *		control or the fragment number is not zero.  Only set when
 *		first_msdu is set.
 *
 * order
 *		Set if the order bit in the frame control is set.  Only set
 *		when first_msdu is set.
 *
 * cce_match
 *		Indicates that this status has a corresponding MSDU that
 *		requires FW processing. The OLE will have classification
 *		ring mask registers which will indicate the ring(s) for
 *		packets and descriptors which need FW attention.
 *
 * overflow_err
 *		PCU Receive FIFO does not have enough space to store the
 *		full receive packet.  Enough space is reserved in the
 *		receive FIFO for the status is written.  This MPDU remaining
 *		packets in the PPDU will be filtered and no Ack response
 *		will be transmitted.
 *
 * msdu_length_err
 *		Indicates that the MSDU length from the 802.3 encapsulated
 *		length field extends beyond the MPDU boundary.
 *
 * tcp_udp_chksum_fail
 *		Indicates that the computed checksum (tcp_udp_chksum) did
 *		not match the checksum in the TCP/UDP header.
 *
 * ip_chksum_fail
 *		Indicates that the computed checksum did not match the
 *		checksum in the IP header.
 *
 * sa_idx_invalid
 *		Indicates no matching entry was found in the address search
 *		table for the source MAC address.
 *
 * da_idx_invalid
 *		Indicates no matching entry was found in the address search
 *		table for the destination MAC address.
 *
 * rx_in_tx_decrypt_byp
 *		Indicates that RX packet is not decrypted as Crypto is busy
 *		with TX packet processing.
 *
 * 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.
 *
 * 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.
 *
 * mpdu_length_err
 *		Indicates that the MPDU was pre-maturely terminated
 *		resulting in a truncated MPDU.  Don't trust the MPDU length
 *		field.
 *
 * tkip_mic_err
 *		Indicates that the MPDU Michael integrity check failed
 *
 * decrypt_err
 *		Indicates that the MPDU decrypt integrity check failed
 *
 * fcs_err
 *		Indicates that the MPDU FCS check failed
 *
 * flow_idx_timeout
 *		Indicates an unsuccessful flow search due to the expiring of
 *		the search timer.
 *
 * flow_idx_invalid
 *		flow id is not valid.
 *
 * amsdu_parser_error
 *		A-MSDU could not be properly de-agregated.
 *
 * sa_idx_timeout
 *		Indicates an unsuccessful search for the source MAC address
 *		due to the expiring of the search timer.
 *
 * da_idx_timeout
 *		Indicates an unsuccessful search for the destination MAC
 *		address due to the expiring of the search timer.
 *
 * msdu_limit_error
 *		Indicates that the MSDU threshold was exceeded and thus
 *		all the rest of the MSDUs will not be scattered and will not
 *		be decasulated but will be DMA'ed in RAW format as a single
 *		MSDU buffer.
 *
 * 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 or Broadcast address.
 *
 * sa_is_valid
 *		Indicates that OLE found a valid SA entry.
 *
 * decrypt_status_code
 *		Field provides insight into the decryption performed. Values are
 *		defined in enum %RX_DESC_DECRYPT_STATUS_CODE*.
 *
 * rx_bitmap_not_updated
 *		Frame is received, but RXPCU could not update the receive bitmap
 *		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
 *		start/end descriptors and RX Attention descriptor are all
 *		valid.  This bit must be in the last octet of the
 *		descriptor.

 *		Note: for ndp frame, if it was expected because the preceding
 *		NDPA was filter_pass, the setting rxpcu_filter_pass will be
 *		used. This setting will also be used for every ndp frame in
 *		case Promiscuous mode is enabled.

 *		REO shall drop this MSDU and not forward it to any other ring.
 *
 * reo_destination_indication
 *		The id of the reo exit ring where the msdu frame shall push
