phy_ppdu_id

			A ppdu counter value that PHY increments for every PPDU
			received. The counter value wraps around

			<legal all>

user_rssi

			RSSI for this user

			Frequency domain RSSI measurement for this user. Based
			on the channel estimate.


			<legal all>

pkt_type

			Packet type:


			<enum 0 dot11a>802.11a PPDU type

			<enum 1 dot11b>802.11b PPDU type

			<enum 2 dot11n_mm>802.11n Mixed Mode PPDU type

			<enum 4 dot11ax>802.11ax PPDU type

			<enum 5 dot11ba>802.11ba (WUR) PPDU type

stbc

			When set, use STBC transmission rates

reception_type

			Indicates what type of reception this is.

			<enum 0     reception_type_SU > Basic SU reception (not
			part of OFDMA or MU-MIMO)

			<enum 1     reception_type_MU_MIMO > This is related to
			DL type of reception

			<enum 2     reception_type_MU_OFDMA >  This is related
			to DL type of reception

			<enum 3     reception_type_MU_OFDMA_MIMO >  This is
			related to DL type of reception

			related to UL type of reception

			<enum 6     reception_type_UL_MU_OFDMA_MIMO >  This is
			related to UL type of reception


			<legal 0-6>

rate_mcs

			For details, refer to  MCS_TYPE description

			<legal all>

sgi

			Field only valid when pkt type is HT, VHT or HE.


			<enum 0     gi_0_8_us > Legacy normal GI.  Can also be
			used for HE

			<enum 1     gi_0_4_us > Legacy short GI.  Can also be
			used for HE

			<enum 2     gi_1_6_us > HE related GI

			<enum 3     gi_3_2_us > HE related GI

mimo_ss_bitmap

			Bitmap, with each bit indicating if the related spatial
			stream is used for this STA

			LSB related to SS 0


			0: spatial stream not used for this reception

			1: spatial stream used for this reception


			<legal all>

ofdma_ru_allocation

			Field only valid in case of OFDMA type receptions (DL
			and UL)


			Indicates the RU number associated with this user.


			In case of reception where the transmission was DL MU
			OFDMA, this field provides the RU pattern. Note that fields
			ofdma_user_index and ofdma_content_channel are needed to
			determine which RU (within a 40 MHz channel) was actually
			assigned to this user, but this does not give info on which
			40 MHz channel was assigned to this user. Please refer
			DL_ofdma_ru_* in PHYRX_PKT_END_INFO for complete RU info for
			this user.


			In case of reception where the transmission was UL MU
			OFDMA, PHY is recommended to insert the RU start index in
			this field. Note that PHY may insert the RU width in
			Reserved_2a[6:0].

			<legal all>

ofdma_user_index

			Field only valid in the of DL MU OFDMA reception


			The user number within the RU_allocation.


			This is needed for SW to determine the exact RU position
			within the reception.

			<legal all>

ofdma_content_channel

			Field only valid in the of DL MU OFDMA/MIMO reception


			In case of DL MU reception, this field indicates the
			content channel number where PHY found the RU information
			for this user


			This is needed for SW to determine the exact RU position
			within the reception.


			<enum 0      content_channel_1>

			<enum 1      content_channel_2>


			<legal all>

ldpc

			When set, use LDPC transmission rates were used.

			<legal all>

ru_width

			In case of UL OFDMA reception, PHY is recommended to
			insert the RU width

			In Hastings80: was using Reserved_2a[6:0].
