/*

msdu_count

			Consumer: REO/SW/FW

			Producer: RXDMA



			The number of MSDUs within the MPDU

			<legal all>

mpdu_sequence_number

			Consumer: REO/SW/FW

			Producer: RXDMA



			The field can have two different meanings based on the
			setting of field 'BAR_frame':



			'BAR_frame' is NOT set:

			The MPDU sequence number of the received frame.



			'BAR_frame' is set.

			The MPDU Start sequence number from the BAR frame

			<legal all>

fragment_flag

			Consumer: REO/SW/FW

			Producer: RXDMA



			When set, this MPDU is a fragment and REO should forward
			this fragment MPDU to the REO destination ring without any
			reorder checks, pn checks or bitmap update. This implies
			that REO is forwarding the pointer to the MSDU link
			descriptor. The destination ring is coming from a
			programmable register setting in REO



			<legal all>

mpdu_retry_bit

			Consumer: REO/SW/FW

			Producer: RXDMA



			The retry bit setting from the MPDU header of the
			received frame

			<legal all>

ampdu_flag

			Consumer: REO/SW/FW

			Producer: RXDMA



			When set, the MPDU was received as part of an A-MPDU.

			<legal all>

bar_frame

			Consumer: REO/SW/FW

			Producer: RXDMA



			When set, the received frame is a BAR frame. After
			processing, this frame shall be pushed to SW or deleted.

			<legal all>

pn_fields_contain_valid_info

			Consumer: REO/SW/FW

			Producer: RXDMA



			Copied here by RXDMA from RX_MPDU_END

			When not set, REO will Not perform a PN sequence number
			check

sa_is_valid

			When set, OLE found a valid SA entry for all MSDUs in
			this MPDU

			<legal all>

sa_idx_timeout

			When set, at least 1 MSDU within the MPDU has an
			unsuccessful MAC source address search due to the expiration
			of the search timer.

			<legal all>

da_is_valid

			When set, OLE found a valid DA entry for all MSDUs in
			this MPDU

			<legal all>

da_is_mcbc

			Field Only valid if da_is_valid is set



			When set, at least one of the DA addresses is a
			Multicast or Broadcast address.

			<legal all>

da_idx_timeout

			When set, at least 1 MSDU within the MPDU has an
			unsuccessful MAC destination address search due to the
			expiration of the search timer.

			<legal all>

raw_mpdu

			Field only valid when first_msdu_in_mpdu_flag is set.



			When set, the contents in the MSDU buffer contains a
			'RAW' MPDU. This 'RAW' MPDU might be spread out over
			multiple MSDU buffers.

			<legal all>

more_fragment_flag

			The More Fragment bit setting from the MPDU header of
			the received frame



			<legal all>

peer_meta_data

			Meta data that SW has programmed in the Peer table entry
			of the transmitting STA.

			<legal all>
