The header + file include/wmi.h contains all command and event manifest constants as + well as structure typedefs for each set of command and reply parameters. + +Data Frames + + The data payload transmitted and received by the target follows RFC-1042 + encapsulation and thus starts with an 802.2-style LLC-SNAP header. The + WLAN module completes 802.11 encapsulation of the payload, including the + MAC header, FCS, and WLAN security related fields. At the interface to the + message transport (HTC), a data frame is encapsulated in a WMI message. + +WMI Message Structure + + The WMI protocol leverages an 802.3-style Ethernet header in communicating + the source and destination information between the host and the AR6000 + modules using a 14-byte 802.3 header ahead of the 802.2-style payload. In + addition, the WMI protocol adds a header to all data messages: + + { + INT8 rssi + The RSSI of the received packet and its units are shown in db above the + noise floor, and the noise floor is shown in dbm. + UINT8 info + Contains information on message type and user priority. Message type + differentiates between a data packet and a synchronization message. + } WMI_DATA_HDR + + User priority contains the 802.1d user priority info from host to target. Host + software translates the host Ethernet format to 802.3 format prior to Tx and + 802.3 format to host format in the Rx direction. The host does not transmit the + FCS that follows the data. MsgType differentiates between a regular data + packet (msgType=0) and a synchronization message (msgType=1). + +Data Endpoints + + The AR6000 chipset provides several data endpoints to support quality of + service (QoS) and maintains separate queues and separate DMA engines for + each data endpoint. A data endpoint can be bi-directional. + + Best effort (BE) class traffic uses the default data endpoint (2). The host can + establish up to two additional data endpoints for other traffic classes. Once + such a data endpoint is established, it sends and receives corresponding QoS + traffic in a manner similar to the default data endpoint. + + If QoS is desired over the interconnect, host software must classify each data + packet and place it on the appropriate data endpoint. The information + required to classify data is generally available in-band as an 802.1p/q style + tag or as the ToS field in the IP header. The information may also be available + out-of-band depending on the host DDI. + +Connection States + + Table B-1 describes the AR6000 WLAN connection states: + + Table B-1. AR6000 Connection States + +Connection State + Description + + DISCONNECTED + In this state, the AR6000 device is not connected to a wireless + network. The device is in this state after reset when it sends the + WIRELESS MODULE “READY” EVENT, after it processes a + DISCONNECT command, and when it loses its link with the + access point (AP) that it was connected to. The device signals a + transition to the DISCONNECTED state with a “DISCONNECT” + event. + +CONNECTED + In this state, the AR6000 device is connected to wireless networks. + The device enters this state after successfully processing a + CONNECT, which establishes a connection with a wireless + network. The device signals a transition to the CONNECTED state + with a “CONNECT” event. + + +Message Types + + WMI uses commands, replies, and events for the control and configuration of + the AR6000 device. The control protocol is asynchronous. Table B-2 describes + AR6000 message types: + +Table B-2. AR6000 Message Types + +Message Type + Description + +Commands + Control messages that flow from the host to the device + +Replies/Events + Control messages that flow from the device to the host. + + The device issues a reply to some WMI commands, but not to others. + The payload in a reply is command-specific, and some commands do + not trigger a reply message at all. Events are control messages issued + by the device to signal the occurrence of an asynchronous event. + + +WMI Message Format + + All WMI control commands, replies and events use the header format: + + WMI_CMD_HDR Header Format + { + UINT16 id + This 16-bit constant identifies which WMI command the host is issuing, + which command the target is replying to, or which event has occurred. + WMI_CMD_HDR + } + + + A variable-size command-, reply-, or event-specific payload follows the + header. Over the interconnect, all fields in control messages (including + WMI_CMD_HDR and the command specific payload) use 32-bit little Endian + byte ordering and fields are packed. The AR6000 device always executes + commands in order, and the host may send multiple commands without + waiting for previous commands to complete. A majority of commands are + processed to completion once received. Other commands trigger a longer + duration activity whose completion is signaled to the host through an event. + +Command Restrictions + + Some commands may only be issued when the AR6000 device is in a certain + state. The host is required to wait for an event signaling a state transition + before such a command can be issued. For example, if a command requires + the device to be in the CONNECTED state, then the host is required to wait + for a “CONNECT” event before it issues that command. + + The device ignores any commands inappropriate for its current state. If the + command triggers a reply, the device generates an error reply. Otherwise, the + device silently ignores the inappropriate command. + +Command and Data Synchronization + + WMI provides a mechanism for a host to advise the device of necessary + synchronization between commands and data. The device implements + synchronization; no implicit synchronization exists between endpoints. + + The host controls synchronization using the “SYNCHRONIZE” command + over the control channel and synchronization messages over data channels. + The device stops each data channel upon receiving a synchronization message + on that channel, processing all data packets received prior to that message. + After the device receives synchronization messages for each data endpoint + and the “SYNCHRONIZE” command, it resumes all channels. + + When the host must guarantee a command executes before processing new + data packets, it first issues the command, then issues the “SYNCHRONIZE” + command and sends synchronization messages on data channels. When the + host must guarantee the device has processed all old data packets before a + processing a new command, it issues a “SYNCHRONIZE” command and + synchronization messages on all data channels, then issues the desired + command. + + + +WMI Commands + + ADD_BAD_AP + Cause the AR6000 device to avoid a particular AP + ADD_CIPHER_KEY + Add or replace any of the four AR6000 encryption keys + ADD_WOW_PATTERN + Used to add a pattern to the WoW pattern list + CLR_RSSI_SNR + Clear the current calculated RSSI and SNR value + CONNECT_CMD + Request that the AR6000 device establish a wireless connection + with the specified SSID + CREATE_PSTREAM + Create prioritized data endpoint between the host and device + DELETE_BAD_AP + Clear an entry in the bad AP table + DELETE_CIPHER_KEY + Delete a previously added cipher key + DELETE_PSTREAM + Delete a prioritized data endpoint + DELETE_WOW_PATTERN + Remove a pre-specified pattern from the WoW pattern list + EXTENSION + WMI message interface command + GET_BIT_RATE + Retrieve rate most recently used by the AR6000 + GET_CHANNEL_LIST + Retrieve list of channels used by the AR6000 + GET_FIXRATES + Retrieves the rate-mask set via the SET_FIXRATES command. + GET_PMKID_LIST_CMD + Retrieve the firmware list of PMKIDs + GET_ROAM_DATA + Internal use for data collection;
