/*
 * HTT version history:
 * 1.0  initial numbered version
 * 1.1  modifications to STATS messages.
 *      These modifications are not backwards compatible, but since the
 *      STATS messages themselves are non-essential (they are for debugging),
 *      the 1.1 version of the HTT message library as a whole is compatible
 *      with the 1.0 version.
 * 1.2  reset mask IE added to STATS_REQ message
 * 1.3  stat config IE added to STATS_REQ message
 *----
 * 2.0  FW rx PPDU desc added to RX_IND message
 * 2.1  Enable msdu_ext/frag_desc banking change for WIFI2.0
 *----
 * 3.0  Remove HTT_H2T_MSG_TYPE_MGMT_TX message
 * 3.1  Added HTT_T2H_MSG_TYPE_RX_IN_ORD_PADDR_IND message
 * 3.2  Added HTT_H2T_MSG_TYPE_WDI_IPA_CFG,
 *            HTT_H2T_MSG_TYPE_WDI_IPA_OP_REQUEST messages
 * 3.3  Added HTT_H2T_MSG_TYPE_AGGR_CFG_EX message
 * 3.4  Added tx_compl_req flag in HTT tx descriptor
 * 3.5  Added flush and fail stats in rx_reorder stats structure
 * 3.6  Added frag flag in HTT RX INORDER PADDR IND header
 * 3.7  Made changes to support EOS Mac_core 3.0
 * 3.8  Added txq_group information element definition;
 *      added optional txq_group suffix to TX_CREDIT_UPDATE_IND message
 * 3.9  Added HTT_T2H CHAN_CHANGE message;
 *      Allow buffer addresses in bus-address format to be stored as
 *      either 32 bits or 64 bits.
 * 3.10 Add optional TLV extensions to the VERSION_REQ and VERSION_CONF
 *      messages to specify which HTT options to use.
 *      Initial TLV options cover:
 *        - whether to use 32 or 64 bits to represent LL bus addresses
 *        - whether to use TX_COMPL_IND or TX_CREDIT_UPDATE_IND in HL systems
 *        - how many tx queue groups to use
 * 3.11 Expand rx debug stats:
 *        - Expand the rx_reorder_stats struct with stats about successful and
 *          failed rx buffer allcoations.
 *        - Add a new rx_remote_buffer_mgmt_stats struct with stats about
 *          the supply, allocation, use, and recycling of rx buffers for the
 *          "remote ring" of rx buffers in host member in LL systems.
 *          Add RX_REMOTE_RING_BUFFER_INFO stats type for uploading these stats.
 * 3.12 Add "rx offload packet error" message with initial "MIC error" subtype
 * 3.13 Add constants + macros to support 64-bit address format for the
 *      tx fragments descriptor, the rx ring buffer, and the rx ring
 *      index shadow register.
 * 3.14 Add a method for the host to provide detailed per-frame tx specs:
 *        - Add htt_tx_msdu_desc_ext_t struct def.
 *        - Add TLV to specify whether the target supports the HTT tx MSDU
 *          extension descriptor.
 *        - Change a reserved bit in the HTT tx MSDU descriptor to an
 *          "extension" bit, to specify whether a HTT tx MSDU extension
 *          descriptor is present.
 * 3.15 Add HW rx desc info to per-MSDU info elems in RX_IN_ORD_PADDR_IND msg.
 *      (This allows the host to obtain key information about the MSDU
 *      from a memory location already in the cache, rather than taking a
 *      cache miss for each MSDU by reading the HW rx descs.)
 * 3.16 Add htt_pkt_type_eth2 and define pkt_subtype flags to indicate
 *      whether a copy-engine classification result is appended to TX_FRM.
 * 3.17 Add a version of the WDI_IPA_CFG message; add RX_RING2 to WDI_IPA_CFG
 * 3.18 Add a PEER_DEL tx completion indication status, for HL cleanup of
 *      tx frames in the target after the peer has already been deleted.
 * 3.19 Add HTT_DBG_STATS_RX_RATE_INFO_V2 and HTT_DBG_STATS_TX_RATE_INFO_V2
 * 3.20 Expand rx_reorder_stats.
 * 3.21 Add optional rx channel spec to HL RX_IND.
 * 3.22 Expand rx_reorder_stats
 *      (distinguish duplicates within vs. outside block ack window)
 * 3.23 Add HTT_T2H_MSG_TYPE_RATE_REPORT to report peer justified rate.
 *      The justified rate is calculated by two steps. The first is to multiply
 *      user-rate by (1 - PER) and the other is to smooth the step 1's result
 *      by a low pass filter.
 *      This change allows HL download scheduling to consider the WLAN rate
 *      that will be used for transmitting the downloaded frames.
 * 3.24 Expand rx_reorder_stats
 *      (add counter for decrypt / MIC errors)
 * 3.25 Expand rx_reorder_stats
 *      (add counter of frames received into both local + remote rings)
 * 3.26 Add stats struct for counting rx of tx BF, MU, SU, and NDPA frames
 *      (HTT_DBG_STATS_TXBF_MUSU_NDPA_PKT, rx_txbf_musu_ndpa_pkts_stats)
 * 3.27 Add a new interface for flow-control. The following t2h messages have
 *      been included: HTT_T2H_MSG_TYPE_FLOW_POOL_MAP and
 *      HTT_T2H_MSG_TYPE_FLOW_POOL_UNMAP

/*=== HTT option selection TLVs ===
 * Certain HTT messages have alternatives or options.
 * For such cases, the host and target need to agree on which option to use.
 * Option specification TLVs can be appended to the VERSION_REQ and
 * VERSION_CONF messages to select options other than the default.
 * These TLVs are entirely optional - if they are not provided, there is a
 * well-defined default for each option.  If they are provided, they can be
 * provided in any order.  Each TLV can be present or absent independent of
 * the presence / absence of other TLVs.
 *
 * The HTT option selection TLVs use the following format:
 *     |31                             16|15             8|7              0|
 *     |---------------------------------+----------------+----------------|
 *     |        value (payload)          |     length     |       tag      |
 *     |-------------------------------------------------------------------|
 * The value portion need not be only 2 bytes; it can be extended by any
 * integer number of 4-byte units.  The total length of the TLV, including
 * the tag and length fields, must be a multiple of 4 bytes.  The length
 * field specifies the total TLV size in 4-byte units.  Thus, the typical
 * TLV, with a 1-byte tag field, a 1-byte length field, and a 2-byte value
 * field, would store 0x1 in its length field, to show that the TLV occupies
 * a single 4-byte unit.

 * @brief HTT tx MSDU descriptor
 *
 * @details
 *  The HTT tx MSDU descriptor is created by the host HTT SW for each
 *  tx MSDU.  The HTT tx MSDU descriptor contains the information that
 *  the target firmware needs for the FW's tx processing, particularly
 *  for creating the HW msdu descriptor.
 *  The same HTT tx descriptor is used for HL and LL systems, though
 *  a few fields within the tx descriptor are used only by LL or
 *  only by HL.
 *  The HTT tx descriptor is defined in two manners: by a struct with
 *  bitfields, and by a series of [dword offset, bit mask, bit shift]
 *  definitions.
 *  The target should use the struct def, for simplicitly and clarity,
 *  but the host shall use the bit-mast + bit-shift defs, to be endian-
 *  neutral.  Specifically, the host shall use the get/set macros built
 *  around the mask + shift defs.

	 *
	 * For HT / VHT preamble types, this mask directly corresponds to
	 * the HT or VHT MCS indices that are allowed.  For each bit N set
	 * within the mask, MCS index N is allowed for transmitting the frame.
	 * For legacy CCK and OFDM rates, separate bits are provided for CCK
	 * rates versus OFDM rates, so the host has the option of specifying
	 * that the target must transmit the frame with CCK or OFDM rates
	 * (not HT or VHT), but leaving the decision to the target whether
	 * to use CCK or OFDM.
	 *
	 * For CCK and OFDM, the bits within this mask are interpreted as
	 * follows:
	 *     bit  0 -> CCK 1 Mbps rate is allowed
	 *     bit  1 -> CCK 2 Mbps rate is allowed
	 *     bit  2 -> CCK 5.5 Mbps rate is allowed
	 *     bit  3 -> CCK 11 Mbps rate is allowed
	 *     bit  4 -> OFDM BPSK modulation, 1/2 coding rate is allowed
	 *     bit  5 -> OFDM BPSK modulation, 3/4 coding rate is allowed
	 *     bit  6 -> OFDM QPSK modulation, 1/2 coding rate is allowed
	 *     bit  7 -> OFDM QPSK modulation, 3/4 coding rate is allowed
	 *     bit  8 -> OFDM 16-QAM modulation, 1/2 coding rate is allowed
	 *     bit  9 -> OFDM 16-QAM modulation, 3/4 coding rate is allowed
	 *     bit 10 -> OFDM 64-QAM modulation, 2/3 coding rate is allowed
	 *     bit 11 -> OFDM 64-QAM modulation, 3/4 coding rate is allowed
	 *
	 * The MCS index specification needs to be compatible with the
	 * bandwidth mask specification.  For example, a MCS index == 9
	 * specification is inconsistent with a preamble type == VHT,
	 * Nss == 1, and channel bandwidth == 20 MHz.
	 *
	 * Furthermore, the host has only a limited ability to specify to
	 * the target to select from HT + legacy rates, or VHT + legacy rates,
	 * since this mcs_mask can specify either HT/VHT rates or legacy rates.

/**
 * @brief MAC DMA rx ring setup specification
 * @details
 *  To allow for dynamic rx ring reconfiguration and to avoid race
 *  conditions, the host SW never directly programs the MAC DMA rx ring(s)
 *  it uses.  Instead, it sends this message to the target, indicating how
 *  the rx ring used by the host should be set up and maintained.
 *  The message consists of a 4-octet header followed by 1 or 2 rx ring setup
 *  specifications.

/**
 * @brief host -> target HTT out-of-band sync request
 *
 * @details
 *  The HTT SYNC tells the target to suspend processing of subsequent
 *  HTT host-to-target messages until some other target agent locally
 *  informs the target HTT FW that the current sync counter is equal to
 *  or greater than (in a modulo sense) the sync counter specified in
 *  the SYNC message.
 *  This allows other host-target components to synchronize their operation
 *  with HTT, e.g. to ensure that tx frames don't get transmitted until a
 *  security key has been downloaded to and activated by the target.
 *  In the absence of any explicit synchronization counter value
 *  specification, the target HTT FW will use zero as the default current
 *  sync value.

/**
 * @brief HTT WDI_IPA Config Message
 *
 * @details
 *  The HTT WDI_IPA config message is created/sent by host at driver
 *  init time. It contains information about data structures used on
 *  WDI_IPA TX and RX path.
 *  TX CE ring is used for pushing packet metadata from IPA uC
 *  to WLAN FW
 *  TX Completion ring is used for generating TX completions from
 *  WLAN FW to IPA uC
 *  RX Indication ring is used for indicating RX packets from FW
 *  to IPA uC
 *  RX Ring2 is used as either completion ring or as second
 *  indication ring. when Ring2 is used as completion ring, IPA uC
 *  puts completed RX packet meta data to Ring2. when Ring2 is used
 *  as second indication ring, RX packets for LTE-WLAN aggregation are
 *  indicated in Ring2, other RX packets (e.g. hotspot related) are
 *  indicated in RX Indication ring. Please see WDI_IPA specification
 *  for more details.

/**
 * @brief target -> host rx indication message definition
 *
 * @details
 * The following field definitions describe the format of the rx indication
 * message sent from the target to the host.
 * The message consists of three major sections:
 * 1.  a fixed-length header
 * 2.  a variable-length list of firmware rx MSDU descriptors
 * 3.  one or more 4-octet MPDU range information elements
 * The fixed length header itself has two sub-sections
 * 1.  the message meta-information, including identification of the
 *     sender and type of the received data, and a 4-octet flush/release IE
 * 2.  the firmware rx PPDU descriptor
 *
 * The format of the message is depicted below.
 * in this depiction, the following abbreviations are used for information
 * elements within the message:
 *   - SV - start valid: this flag is set if the FW rx PPDU descriptor
 *          elements associated with the PPDU start are valid.
 *          Specifically, the following fields are valid only if SV is set:
 *              RSSI (all variants), L, legacy rate, preamble type, service,
 *              VHT-SIG-A
 *   - EV - end valid: this flag is set if the FW rx PPDU descriptor
 *          elements associated with the PPDU end are valid.
 *          Specifically, the following fields are valid only if EV is set:
 *              P, PHY err code, TSF, microsec / sub-microsec timestamp
 *   - L  - Legacy rate selector - if legacy rates are used, this flag
 *          indicates whether the rate is from a CCK (L == 1) or OFDM
 *          (L == 0) PHY.
 *   - P  - PHY error flag - boolean indication of whether the rx frame had
 *          a PHY error

 *     Purpose: indicate whether the flush IE (start/end sequence numbers)
 *         is valid
 *     Value:
 *         1 -> flush IE is valid and needs to be processed
 *         0 -> flush IE is not valid and should be ignored

 *     Purpose: Identify, by ID, which peer sent the rx data
 *     Value: ID of the peer who sent the rx data
 *   - FLUSH_SEQ_NUM_START
 *     Bits 5:0
 *     Purpose: Indicate the start of a series of MPDUs to flush
 *         Not all MPDUs within this series are necessarily valid - the host
 *         must check each sequence number within this range to see if the
 *         corresponding MPDU is actually present.
 *         This field is only valid if the FV bit is set.
 *     Value:
 *         The sequence number for the first MPDUs to check to flush.
 *         The sequence number is masked by 0x3f.

 *         last MPDU to check to flush.
 *         The sequence number is masked by 0x3f.
 *         Not all MPDUs within this series are necessarily valid - the host
 *         must check each sequence number within this range to see if the
 *         corresponding MPDU is actually present.
 *         This field is only valid if the FV bit is set.
 *   - REL_SEQ_NUM_START
 *     Bits 17:12
 *     Purpose: Indicate the start of a series of MPDUs to release.
 *         All MPDUs within this series are present and valid - the host
 *         need not check each sequence number within this range to see if
 *         the corresponding MPDU is actually present.
 *         This field is only valid if the RV bit is set.
 *     Value:
 *         The sequence number for the first MPDUs to check to release.
 *         The sequence number is masked by 0x3f.
 *   - REL_SEQ_NUM_END
 *     Bits 23:18
 *     Purpose: Indicate the end of a series of MPDUs to release.
 *     Value:
 *         The sequence number one larger than the sequence number of the
 *         last MPDU to check to release.
 *         The sequence number is masked by 0x3f.
 *         All MPDUs within this series are present and valid - the host
 *         need not check each sequence number within this range to see if
 *         the corresponding MPDU is actually present.
 *         This field is only valid if the RV bit is set.
 *   - NUM_MPDU_RANGES
 *     Bits 31:24
 *     Purpose: Indicate how many ranges of MPDUs are present.
 *         Each MPDU range consists of a series of contiguous MPDUs within the
 *         rx frame sequence which all have the same MPDU status.
 *     Value: 1-63 (typically a small number, like 1-3)
 *
 * Rx PPDU descriptor fields:
 *   - RSSI_CMB
 *     Bits 7:0
 *     Purpose: Combined RSSI from all active rx chains, across the active
 *         bandwidth.
 *     Value: RSSI dB units w.r.t. noise floor
 *   - TIMESTAMP_SUBMICROSEC
 *     Bits 15:8
 *     Purpose: high-resolution timestamp
 *     Value:

 *         This field is valid if the "P" (PHY_ERR) flag is set.
 *         TBD: document/specify the values for this field
 *   - PHY_ERR
 *     Bit 24
 *     Purpose: indicate whether the rx PPDU had a PHY error
 *     Value: 0 -> no rx PHY error, 1 -> rx PHY error encountered
 *   - LEGACY_RATE
 *     Bits 28:25
 *     Purpose:
 *         If the rx frame used a legacy rate rather than a HT or VHT rate,
 *         specify which rate was used.
 *     Value:
 *         The LEGACY_RATE field's value depends on the "L" (LEGACY_RATE_SEL)
 *         flag.
 *         If LEGACY_RATE_SEL is 0:
 *             0x8: OFDM 48 Mbps
 *             0x9: OFDM 24 Mbps
 *             0xA: OFDM 12 Mbps
 *             0xB: OFDM 6 Mbps
 *             0xC: OFDM 54 Mbps
 *             0xD: OFDM 36 Mbps
 *             0xE: OFDM 18 Mbps
 *             0xF: OFDM 9 Mbps
 *         If LEGACY_RATE_SEL is 1:

 * @brief target -> host rx offload deliver message for LL system

 * In a low latency system this message is sent whenever the offload

 * The DMA of the actual packets into host memory is done before sending out
 * this message. This message indicates only how many MSDUs to reap. The
 * peer ID, vdev ID, tid and MSDU length are copied inline into the header
 * portion of the MSDU while DMA'ing into the host memory. Unlike the packets
 * DMA'd by the MAC directly into host memory these packets do not contain
 * the MAC descriptors in the header portion of the packet. Instead they contain
 * the peer ID, vdev ID, tid and MSDU length. Also when the host receives this
 * message, the packets are delivered directly to the NW stack without going
 * through the regular reorder buffering and PN checking path since it has
 * already been done in target.

/**
 * @brief tx queue group information element definition
 *
 * @details
 * The following diagram shows the format of the tx queue group
 * information element, which can be included in target --> host
 * messages to specify the number of tx "credits" (tx descriptors
 * for LL, or tx buffers for HL) available to a particular group
 * of host-side tx queues, and which host-side tx queues belong to
 * the group.
 *
 * |31|30          24|23             16|15|14|13                           0|
 * |------------------------------------------------------------------------|
 * | X|   reserved   | tx queue grp ID | A| S|     credit count             |
 * |------------------------------------------------------------------------|
 * |            vdev ID mask           |               AC mask              |
 * |------------------------------------------------------------------------|
 *
 * The following definitions describe the fields within the tx queue group
 * information element:
 * - credit_count
 *   Bits 13:1
 *   Purpose: specify how many tx credits are available to the tx queue group
 *   Value: An absolute or relative, positive or negative credit value
 *       The 'A' bit specifies whether the value is absolute or relative.
 *       The 'S' bit specifies whether the value is positive or negative.
 *       A negative value can only be relative, not absolute.
 *       An absolute value replaces any prior credit value the host has for
 *       the tx queue group in question.
 *       A relative value is added to the prior credit value the host has for
 *       the tx queue group in question.
 * - sign
 *   Bit 14
 *   Purpose: specify whether the credit count is positive or negative
 *   Value: 0 -> positive, 1 -> negative
 * - absolute
 *   Bit 15
 *   Purpose: specify whether the credit count is absolute or relative
 *   Value: 0 -> relative, 1 -> absolute
 * - txq_group_id
 *   Bits 23:16
 *   Purpose: indicate which tx queue group's credit and/or membership are
 *       being specified
 *   Value: 0 to max_tx_queue_groups-1
 * - reserved
 *   Bits 30:16
 *   Value: 0x0
 * - eXtension
 *   Bit 31
 *   Purpose: specify whether another tx queue group info element follows
 *   Value: 0 -> no more tx queue group information elements
 *          1 -> another tx queue group information element immediately follows
 * - ac_mask
 *   Bits 15:0
 *   Purpose: specify which Access Categories belong to the tx queue group
 *   Value: bit-OR of masks for the ACs (WMM and extension) that belong to
 *       the tx queue group.
 *       The AC bit-mask values are obtained by left-shifting by the
 *       corresponding HTT_AC_WMM enum values, e.g. (1 << HTT_AC_WMM_BE) == 0x1
 * - vdev_id_mask
 *   Bits 31:16
 *   Purpose: specify which vdev's tx queues belong to the tx queue group
 *   Value: bit-OR of masks based on the IDs of the vdevs whose tx queues
 *       belong to the tx queue group.
 *       For example, if vdev IDs 1 and 4 belong to a tx queue group, the
 *       vdev_id_mask would be (1 << 1) | (1 << 4) = 0x12

 * @brief host -> target FRAG DESCRIPTOR/MSDU_EXT DESC bank
 *
 * @details
 * The following field definitions describe the format of the HTT host
 * to target frag_desc/msdu_ext bank configuration message.
 * The message contains the based address and the min and max id of the
 * MSDU_EXT/FRAG_DESC that will be used by the HTT to map MSDU DESC and
 * MSDU_EXT/FRAG_DESC.
 * HTT will use id in HTT descriptor instead sending the frag_desc_ptr.
 * In peregrine the firmware will use fragment_desc_ptr but in WIFI2.0
 * the hardware does the mapping/translation.
 *
 * Total banks that can be configured is configured to 16.
 *
 * This should be called before any TX has be initiated by the HTT
