They offer a higher level API that - * applications should use (an example of this is the Intel's WiMAX - * Network Service for the i2400m). - * - * DESIGN - * - * Although not set on final stone, this very basic interface is - * mostly completed. Remember this is meant to grow as new common - * operations are decided upon. New operations will be added to the - * interface, intent being on keeping backwards compatibility as much - * as possible. - * - * This layer implements a set of calls to control a WiMAX device, - * exposing a frontend to the rest of the kernel and user space (via - * generic netlink) and a backend implementation in the driver through - * function pointers. - * - * WiMAX devices have a state, and a kernel-only API allows the - * drivers to manipulate that state. State transitions are atomic, and - * only some of them are allowed (see `enum wimax_st`). - * - * Most API calls will set the state automatically; in most cases - * drivers have to only report state changes due to external - * conditions. - * - * All API operations are 'atomic', serialized through a mutex in the - * `struct wimax_dev`. - * - * EXPORTING TO USER SPACE THROUGH GENERIC NETLINK - * - * The API is exported to user space using generic netlink (other - * methods can be added as needed). - * - * There is a Generic Netlink Family named "WiMAX", where interfaces - * supporting the WiMAX interface receive commands and broadcast their - * signals over a multicast group named "msg". - * - * Mapping to the source/destination interface is done by an interface - * index attribute. - * - * For user-to-kernel traffic (commands) we use a function call - * marshalling mechanism, where a message X with attributes A, B, C - * sent from user space to kernel space means executing the WiMAX API - * call wimax_X(A, B, C), sending the results back as a message. - * - * Kernel-to-user (notifications or signals) communication is sent - * over multicast groups. This allows to have multiple applications - * monitoring them. - * - * Each command/signal gets assigned it's own attribute policy. This - * way the validator will verify that all the attributes in there are - * only the ones that should be for each command/signal. Thing of an - * attribute mapping to a type+argumentname for each command/signal. - * - * If we had a single policy for *all* commands/signals, after running - * the validator we'd have to check "does this attribute belong in - * here"? for each one. It can be done manually, but it's just easier - * to have the validator do that job with multiple policies. As well, - * it makes it easier to later expand each command/signal signature - * without affecting others and keeping the namespace more or less - * sane. Not that it is too complicated, but it makes it even easier. - * - * No state information is maintained in the kernel for each user - * space connection (the connection is stateless). - * - * TESTING FOR THE INTERFACE AND VERSIONING - * - * If network interface X is a WiMAX device, there will be a Generic - * Netlink family named "WiMAX X" and the device will present a - * "wimax" directory in it's network sysfs directory - * (/sys/class/net/DEVICE/wimax) [used by HAL]. - * - * The inexistence of any of these means the device does not support - * this WiMAX API. - * - * By querying the generic netlink controller, versioning information - * and the multicast groups available can be found. Applications using - * the interface can either rely on that or use the generic netlink - * controller to figure out which generic netlink commands/signals are - * supported. - * - * NOTE: this versioning is a last resort to avoid hard - * incompatibilities. It is the intention of the design of this - * stack not to introduce backward incompatible changes. - * - * The version code has to fit in one byte (restrictions imposed by - * generic netlink); we use `version / 10` for the major version and - * `version % 10` for the minor. This gives 9 minors for each major - * and 25 majors. - * - * The version change protocol is as follow: - * - * - Major versions: needs to be increased if an existing message/API - * call is changed or removed. Doesn't need to be changed if a new - * message is added. - * - * - Minor version: needs to be increased if new messages/API calls are - * being added or some other consideration that doesn't impact the - * user-kernel interface too much (like some kind of bug fix) and - * that is kind of left up in the air to common sense. - * - * User space code should not try to work if the major version it was - * compiled for differs from what the kernel offers. As well, if the - * minor version of the kernel interface is lower than the one user - * space is expecting (the one it was compiled for), the kernel - * might be missing API calls; user space shall be ready to handle - * said condition. Use the generic netlink controller operations to - * find which ones are supported and which not. - * - * libwimaxll:wimaxll_open() takes care of checking versions. - * - * THE OPERATIONS: - * - * Each operation is defined in its on file (drivers/net/wimax/op-*.c) - * for clarity. The parts needed for an operation are: - * - * - a function pointer in `struct wimax_dev`: optional, as the - * operation might be implemented by the stack and not by the - * driver. - * - * All function pointers are named wimax_dev->op_*(), and drivers - * must implement them except where noted otherwise. - * - * - When exported to user space, a `struct nla_policy` to define the - * attributes of the generic netlink command and a `struct genl_ops` - * to define the operation. - * - * All the declarations for the operation codes (WIMAX_GNL_OP_<NAME>) - * and generic netlink attributes (WIMAX_GNL_<NAME>_*) are declared in - * include/linux/wimax.h; this file is intended to be cloned by user - * space to gain access to those declarations. - * - * A few caveats to remember: - * - * - Need to define attribute numbers starting in 1; otherwise it - * fails. - * - * - the `struct genl_family` requires a maximum attribute id; when - * defining the `struct nla_policy` for each message, it has to have - * an array size of WIMAX_GNL_ATTR_MAX+1. - * - * The op_*() function pointers will not be called if the wimax_dev is - * in a state <= %WIMAX_ST_UNINITIALIZED. The exception is: - * - * - op_reset: can be called at any time after wimax_dev_add() has - * been called. - * - * THE PIPE INTERFACE: - * - * This interface is kept intentionally simple. The driver can send - * and receive free-form messages to/from user space through a - * pipe. See drivers/net/wimax/op-msg.c for details. - * - * The kernel-to-user messages are sent with - * wimax_msg(). user-to-kernel messages are delivered via - * wimax_dev->op_msg_from_user(). - * - * RFKILL: - * - * RFKILL support is built into the wimax_dev layer; the driver just - * needs to call wimax_report_rfkill_{hw,sw}() to inform of changes in - * the hardware or software RF kill switches. When the stack wants to - * turn the radio off, it will call wimax_dev->op_rfkill_sw_toggle(), - * which the driver implements. - * - * User space can set the software RF Kill switch by calling - * wimax_rfkill(). - * - * The code for now only supports devices that don't require polling; - * If the device needs to be polled, create a self-rearming delayed - * work struct for polling or look into adding polled support to the - * WiMAX stack. - * - * When initializing the hardware (_probe), after calling - * wimax_dev_add(), query the device for it's RF Kill switches status - * and feed it back to the WiMAX stack using - * wimax_report_rfkill_{hw,sw}(). If any switch is missing, always - * report it as ON. - * - * NOTE: the wimax stack uses an inverted terminology to that of the - * RFKILL subsystem: - * - * - ON: radio is ON, RFKILL is DISABLED or OFF. - * - OFF: radio is OFF, RFKILL is ENABLED or ON. - * - * MISCELLANEOUS OPS: - * - * wimax_reset() can be used to reset the device to power on state; by - * default it issues a warm reset that maintains the same device - * node. If that is not possible, it falls back to a cold reset - * (device reconnect).

See drivers/net/wimax/i2400m/fw.c for more - * details. - * - * The BCF data structure is for the firmware file header. - * - * - * THE DATA / CONTROL PROTOCOL - * - * This is the normal protocol spoken with the device once the - * firmware is uploaded. It transports data payloads and control - * messages back and forth. - * - * It consists 'messages' that pack one or more payloads each. The - * format is described in detail in drivers/net/wimax/i2400m/rx.c and - * tx.c. - * - * - * THE L3L4 PROTOCOL - * - * The term L3L4 refers to Layer 3 (the device), Layer 4 (the - * driver/host software). - * - * This is the control protocol used by the host to control the i2400m - * device (scan, connect, disconnect...). This is sent to / received - * as control frames. These frames consist of a header and zero or - * more TLVs with information. We call each control frame a "message". - * - * Each message is composed of: - * - * HEADER - * [TLV0 + PAYLOAD0] - * [TLV1 + PAYLOAD1] - * [...] - * [TLVN + PAYLOADN] - * - * The HEADER is defined by 'struct i2400m_l3l4_hdr'. The payloads are - * defined by a TLV structure (Type Length Value) which is a 'header' - * (struct i2400m_tlv_hdr) and then the payload. - * - * All integers are represented as Little Endian. - * - * - REQUESTS AND EVENTS - * - * The requests can be clasified as follows: - * - * COMMAND: implies a request from the host to the device requesting - * an action being performed. The device will reply with a - * message (with the same type as the command), status and - * no (TLV) payload. Execution of a command might cause - * events (of different type) to be sent later on as - * device's state changes. - * - * GET/SET: similar to COMMAND, but will not cause other - * EVENTs. The reply, in the case of GET, will contain - * TLVs with the requested information. - * - * EVENT: asynchronous messages sent from the device, maybe as a - * consequence of previous COMMANDs but disassociated from - * them. - * - * Only one request might be pending at the same time (ie: don't - * parallelize nor post another GET request before the previous - * COMMAND has been acknowledged with it's corresponding reply by the - * device). - * - * The different requests and their formats are described below: - * - * I2400M_MT_* Message types - * I2400M_MS_* Message status (for replies, events) - * i2400m_tlv_* TLVs - * - * data types are named 'struct i2400m_msg_OPNAME', OPNAME matching the - * operation. - */ - -#ifndef __LINUX__WIMAX__I2400M_H__ -#define __LINUX__WIMAX__I2400M_H__ - -#include <linux/types.h> -#include <linux/if_ether.h> - -/* - * Host Device Interface (HDI) common to all busses - */ - -/* Boot-mode (firmware upload mode) commands */ - -/* Header for the firmware file */ -struct i2400m_bcf_hdr { - __le32 module_type; - __le32 header_len; - __le32 header_version; - __le32 module_id; - __le32 module_vendor; - __le32 date; /* BCD YYYMMDD */ - __le32 size; /* in dwords */ - __le32 key_size; /* in dwords */ - __le32 modulus_size; /* in dwords */ - __le32 exponent_size; /* in dwords */ - __u8 reserved[88]; -} __attribute__ ((packed)); - -/* Boot mode opcodes */ -enum i2400m_brh_opcode { - I2400M_BRH_READ = 1, - I2400M_BRH_WRITE = 2, - I2400M_BRH_JUMP = 3, - I2400M_BRH_SIGNED_JUMP = 8, - I2400M_BRH_HASH_PAYLOAD_ONLY = 9, -}; - -/* Boot mode command masks and stuff */ -enum i2400m_brh { - I2400M_BRH_SIGNATURE = 0xcbbc0000, - I2400M_BRH_SIGNATURE_MASK = 0xffff0000, - I2400M_BRH_SIGNATURE_SHIFT = 16, - I2400M_BRH_OPCODE_MASK = 0x0000000f, - I2400M_BRH_RESPONSE_MASK = 0x000000f0, - I2400M_BRH_RESPONSE_SHIFT = 4, - I2400M_BRH_DIRECT_ACCESS = 0x00000400, - I2400M_BRH_RESPONSE_REQUIRED = 0x00000200, - I2400M_BRH_USE_CHECKSUM = 0x00000100, -}; - - -/** - * i2400m_bootrom_header - Header for a boot-mode command - * - * @cmd: the above command descriptor - * @target_addr: where on the device memory should the action be performed. - * @data_size: for read/write, amount of data to be read/written - * @block_checksum: checksum value (if applicable) - * @payload: the beginning of data attached to this header - */ -struct i2400m_bootrom_header { - __le32 command; /* Compose with enum i2400_brh */ - __le32 target_addr; - __le32 data_size; - __le32 block_checksum; - char payload[0]; -} __attribute__ ((packed)); - - -/* - * Data / control protocol - */ - -/* Packet types for the host-device interface */ -enum i2400m_pt { - I2400M_PT_DATA = 0, - I2400M_PT_CTRL, - I2400M_PT_TRACE, /* For device debug */ - I2400M_PT_RESET_WARM, /* device reset */ - I2400M_PT_RESET_COLD, /* USB[transport] reset, like reconnect */ - I2400M_PT_EDATA, /* Extended RX data */ - I2400M_PT_ILLEGAL -}; - - -/* - * Payload for a data packet - * - * This is prefixed to each and every outgoing DATA type. - */ -struct i2400m_pl_data_hdr { - __le32 reserved; -} __attribute__((packed)); - - -/* - * Payload for an extended data packet - * - * New in fw v1.4 - * - * @reorder: if this payload has to be reorder or not (and how) - * @cs: the type of data in the packet, as defined per (802.16e - * T11.13.19.1).
