 * The following field definitions describe the format of the peer info
 * message sent from the target to the host.
 *
 * WORD 0:
 *   - MSG_TYPE
 *     Bits 7:0
 *     Purpose: identifies this as peer info message
 *     Value: 0x1
 *   - DPU_IDX
 *     Bits 15:8
 *     Purpose: specify the DPU index (a.k.a. security key ID) to use for
 *         unicast data frames sent to this peer
 *     Value: key ID
 *   - BCAST_DPU_IDX
 *     Bits 23:16
 *     Purpose: specify the DPU index (a.k.a. security key ID) to use for
 *         broadcast data frames sent by this (self) peer
 *     Value: key ID
 *   - MGMT_DPU_IDX
 *     Bits 31:24
 *     Purpose: specify the DPU index (a.k.a. security key ID) to use for
 *         unicast management frames sent by this (self) peer
 *     Value: key ID
 * WORD 1:
 *   - PEER_ID
 *     Bits 10:0
 *     Purpose: The ID that the target has allocated to refer to the peer
 *   - DPU_SIG
 *     Bits 17:11
 *     Purpose: specify the DPU signature (a.k.a. security key validity
 *         magic number) to specify for unicast data frames sent to this peer
 *   - BCAST_DPU_SIG
 *     Bits 24:18
 *     Purpose: specify the DPU signature (a.k.a. security key validity
 *         magic number) to specify for broadcast data frames sent by this
 *         (self) peer
 *   - MGMT_DPU_SIG
 *     Bits 31:25
 *     Purpose: specify the DPU signature (a.k.a. security key validity
 *         magic number) to specify for unicast management frames sent by this
 *         (self) peer
 * WORD 2:
 *   - PEER_TYPE
 *     Bits 5:0
 *     Purpose: specify whether the peer in question is a real peer or
 *         one of the types of "self-peer" created for the vdev
 *     Value: HTT_ISOC_T2H_PEER_TYPE enum
 *   - RMF_ENABLED (R)
 *     Bit 6
 *     Purpose: specify whether the peer in question has enable robust
 *         management frames, to encrypt certain managment frames
 *     Value: HTT_ISOC_RMF enum
 *     Value: HTT_ISOC_NON_QOS or HTT_ISOC_QOS
 *   - VDEV_ID
 *     Bits 15:8
 *     Purpose: For a real peer, the vdev ID indicates which virtual device
 *         the peer is associated with.  For a self-peer, the vdev ID shows
 *         which virtual device the self-peer represents.
 *   - MAC_ADDR_L16
 *     Bits 31:16
 *     Purpose: Identifies which peer the peer ID is for.
 *     Value: lower 2 bytes of the peer's MAC address
 *         For a self-peer, the peer's MAC address is the MAC address of the
 *         vdev the self-peer represents.
 * WORD 3:
 *   - MAC_ADDR_U32
 *     Bits 31:0
 *     Purpose: Identifies which peer the peer ID is for.
 *     Value: upper 4 bytes of the peer's MAC address
 *         For a self-peer, the peer's MAC address is the MAC address of the
 *         vdev the self-peer represents.

/**
 * @brief target -> host rx error notification message definition
 *
 * @details
 * The following diagram shows the format of the rx err message sent
 * from the target to the host.  This layout assumes the target operates
 * as little-endian.
 *
 * |31                               16|15              8|7|6|5|4       0|

 * |               peer ID             |   rx err type   |    msg type   |
 * |---------------------------------------------------------------------|
 * |               reserved            |   rx err count  |M| r | ext TID |
 * |---------------------------------------------------------------------|
 * M = multicast
 * r = reserved
 *
 * The following field definitions describe the format of the peer info
 * message sent from the target to the host.
 *
 * WORD 0:
 *   - MSG_TYPE
 *     Bits 7:0
 *     Purpose: identifies this as an rx err message
 *     Value: 0x8
 *   - RX_ERR_TYPE
 *     Bits 15:8
 *     Purpose: specifies which type of rx error is being reported
 *     Value: htt_rx_ind_mpdu_status enum
 *   - PEER_ID
 *     Bits 31:16
 *     Purpose: specify which peer sent the frame that resulted in an error
 * WORD 1:
 *   - EXT_TID
 *     Bits 4:0
 *     Purpose: specifies which traffic type had the rx error
 *     Value: 0-15 for a real TID value, 16 for non-QoS data, 31 for unknown
 *   - MCAST
 *     Bit 6
 *     Purpose: specify whether the rx error frame was unicast or multicast
 *     Value: 0 -> unicast, 1 -> multicast
 *   - L2_HDR_IS_80211
 *     Bit 7
 *     Purpose: specifies whether the included L2 header (if present) is in
 *         802.3 or 802.11 format
 *     Value: 0 -> 802.3, 1 -> 802.11
 *   - L2_HDR_BYTES
 *     Bits 15:8
 *     Purpose: Specify the size of the L2 header in this rx error report.
 *     Value:
 *         If no L2 header is included, this field shall be 0.
 *         If a 802.3 + LLC/SNAP header is included, this field shall be
 *         14 (ethernet header) + 8 (LLC/SNAP).
 *         If a 802.11 header is included, this field shall be 24 bytes for
 *         a basic header, or 26 bytes if a QoS control field is included,
 *         or 30 bytes if a 4th address is included, or 32 bytes if a 4th
 *         address and a QoS control field are included, etc.
 *         Though the L2 header included in the message needs to include
 *         padding up to a 4-byte boundary, this L2 header size field need
 *         not account for the padding following the L2 header.
 *   - SEC_HDR_BYTES
 *     Bits 23:16
 *     Purpose: Specify the size of the security encapsulation header in
 *         this rx error report.
 *     Value:
 *         If no security header is included, this field shall be 0.
 *         If a security header is included, this field depends on the
 *         security type, which can be inferred from the rx error type.
 *         For TKIP MIC errors, the security header could be any of:
 *             8  - if IV / KeyID and Extended IV are included
 *             16 - if MIC is also included
 *             20 - if ICV is also included
 *   - RX_ERR_CNT
 *     Bits 31:24
 *     Purpose: specifies how many rx errors are reported in this message
 *     Value:
 *         Rx error reports that include a L2 header and/or security header
 *         will set this field to 1, to indicate that the error notification
 *         is for a single frame.
 *         Rx error reports that don't include a L2 header or security header
 *         can use this field to send a single message to report multiple
 *         erroneous rx frames.
