 /**
+ * DOC: Frame transmission/registration support
+ *
+ * Frame transmission and registration support exists to allow userspace
+ * management entities such as wpa_supplicant react to management frames
+ * that are not being handled by the kernel. This includes, for example,
+ * certain classes of action frames that cannot be handled in the kernel
+ * for various reasons.
+ *
+ * Frame registration is done on a per-interface basis and registrations
+ * cannot be removed other than by closing the socket. It is possible to
+ * specify a registration filter to register, for example, only for a
+ * certain type of action frame. In particular with action frames, those
+ * that userspace registers for will not be returned as unhandled by the
+ * driver, so that the registered application has to take responsibility
+ * for doing that.
+ *
+ * The type of frame that can be registered for is also dependent on the
+ * driver and interface type. The frame types are advertised in wiphy
+ * attributes so applications know what to expect.
+ *
+ * NOTE: When an interface changes type while registrations are active,
+ *       these registrations are ignored until the interface type is
+ *       changed again. This means that changing the interface type can
+ *       lead to a situation that couldn't otherwise be produced, but
+ *       any such registrations will be dormant in the sense that they
+ *       will not be serviced, i.e. they will not receive any frames.
+ *
+ * Frame transmission allows userspace to send for example the required
+ * responses to action frames. It is subject to some sanity checking,
+ * but many frames can be transmitted. When a frame was transmitted, its
+ * status is indicated to the sending socket.
+ *
+ * For more technical details, see the corresponding command descriptions
+ * below.

+ * struct st_data_s - ST core internal structure
+ * @st_state: different states of ST like initializing, registration
+ *      in progress, this is mainly used to return relevant err codes
+ *      when protocol drivers are registering. It is also used to track
+ *      the recv function, as in during fw download only HCI events
+ *      can occur , where as during other times other events CH8, CH9
+ *      can occur.
+ * @tty: tty provided by the TTY core for line disciplines.
+ * @tx_skb: If for some reason the tty's write returns lesser bytes written
+ *      then to maintain the rest of data to be written on next instance.
+ *      This needs to be protected, hence the lock inside wakeup func.
+ * @tx_state: if the data is being written onto the TTY and protocol driver
+ *      wants to send more, queue up data and mark that there is
+ *      more data to send.
+ * @list: the list of protocols registered, only MAX can exist, one protocol
+ *      can register only once.
+ * @rx_state: states to be maintained inside st's tty receive
+ * @rx_count: count to be maintained inside st's tty receieve
+ * @rx_skb: the skb where all data for a protocol gets accumulated,
+ *      since tty might not call receive when a complete event packet
+ *      is received, the states, count and the skb needs to be maintained.
+ * @txq: the list of skbs which needs to be sent onto the TTY.
+ * @tx_waitq: if the chip is not in AWAKE state, the skbs needs to be queued
+ *      up in here, PM(WAKEUP_IND) data needs to be sent and then the skbs
+ *      from waitq can be moved onto the txq.
+ *      Needs locking too.
+ * @lock: the lock to protect skbs, queues, and ST states.
+ * @protos_registered: count of the protocols registered, also when 0 the
+ *      chip enable gpio can be toggled, and when it changes to 1 the fw
+ *      needs to be downloaded to initialize chip side ST.
+ * @ll_state: the various PM states the chip can be, the states are notified
+ *      to us, when the chip sends relevant PM packets(SLEEP_IND, WAKE_IND).
+ * @kim_data: reference to the parent encapsulating structure.

+ * API through nl80211. For backward compatibility, cfg80211 also offers

+ *
+ * The fundamental structure for each device is the 'wiphy', of which each
+ * instance describes a physical wireless device connected to the system. Each

+ * Explicit TProxy target rule
+ * ===========================
+ *
+ * This is used when the user wants to intercept a connection matching
+ * an explicit iptables rule. In this case the sockets are assumed
+ * matching in preference order:
+ *
+ *   - match: if there's a fully established connection matching the
+ *     _packet_ tuple, it is returned, assuming the redirection
+ *     already took place and we process a packet belonging to an
+ *     established connection
+ *
+ *   - match: if there's a listening socket matching the redirection
+ *     (e.g. on-port & on-ip of the connection), it is returned,
+ *     regardless if it was bound to 0.0.0.0 or an explicit
+ *     address. The reasoning is that if there's an explicit rule, it
+ *     does not really matter if the listener is bound to an interface
+ *     or to 0. The user already stated that he wants redirection
+ *     (since he added the rule).
+ *
+ * "socket" match based redirection (no specific rule)
+ * ===================================================
+ *
+ * There are connections with dynamic endpoints (e.g. FTP data
+ * connection) that the user is unable to add explicit rules
+ * for. These are taken care of by a generic "socket" rule. It is
+ * assumed that the proxy application is trusted to open such
+ * connections without explicit iptables rule (except of course the
+ * generic 'socket' rule). In this case the following sockets are
+ * matched in preference order:
+ *
+ *   - match: if there's a fully established connection matching the
+ *     _packet_ tuple
+ *
+ *   - match: if there's a non-zero bound listener (possibly with a
+ *     non-local address) We don't accept zero-bound listeners, since
+ *     then local services could intercept traffic going through the
+ *     box.
+ *
+ * Please note that there's an overlap between what a TPROXY target
+ * and a socket match will match. Normally if you have both rules the
+ * "socket" match will be the first one, effectively all packets
+ * belonging to established connections going through that one.
