The current naming of rfkill_state causes a lot of confusion: not only the "kill" in rfkill suggests negative logic, but also the fact that rfkill cannot turn anything on (it can just force something off or stop forcing something off) is often forgotten. Rename RFKILL_STATE_OFF to RFKILL_STATE_SOFT_BLOCKED (transmitter is blocked and will not operate; state can be changed by a toggle_radio request), and RFKILL_STATE_ON to RFKILL_STATE_UNBLOCKED (transmitter is not blocked, and may operate). Also, add a new third state, RFKILL_STATE_HARD_BLOCKED (transmitter is blocked and will not operate; state cannot be changed through a toggle_radio request), which is used by drivers to indicate a wireless transmiter was blocked by a hardware rfkill line that accepts no overrides. Keep the old names as #defines, but document them as deprecated. This way, drivers can be converted to the new names *and* verified to actually use rfkill correctly one by one. Signed-off-by:

Rework the documentation so as to make sure driver writers understand exactly where the boundaries are for input drivers related to rfkill switches, buttons and keys, and rfkill class drivers. Also fix a small error in the documentation: setting the state of a normal instance of the rfkill class does not affect the state of any other devices (unless they are tied by firmware/hardware somehow).

SW_RFKILL_ALL is the "emergency power-off all radios" input event. It must be handled, and must always do the same thing as far as the rfkill system is concerned: all transmitters are to go *immediately* offline. For safety, do NOT allow userspace to override EV_SW SW_RFKILL_ALL OFF. As long as rfkill-input is loaded, that event will *always* be processed, and it will *always* force all rfkill switches to disable all wireless transmitters, regardless of user_claim attribute or anything else.

The whole current_state thing seems completely useless and a source of problems in rfkill-input, since state comparison is already done in rfkill, and rfkill-input is more than likely to become out of sync with the real state. Signed-off-by:

Use the notification chains to also send uevents, so that userspace can be notified of state changes of every rfkill switch. Userspace should use these events for OSD/status report applications and rfkill GUI frontends. HAL might want to broadcast them over DBUS, for example. It might be also useful for userspace implementations of rfkill-input, or to use HAL as the platform driver which promotes rfkill switch change events into input events (to synchronize all other switches) when necessary for platforms that lack a convenient platform-specific kernel module to do it.

Add a notifier chain for use by the rfkill class. This notifier chain signals the following events (more to be added when needed): 1. rfkill: rfkill device state has changed A pointer to the rfkill struct will be passed as a parameter. The notifier message types have been added to include/linux/rfkill.h instead of to include/linux/notifier.h in order to avoid the madness of modifying a header used globally (and that triggers an almost full tree rebuild every time it is touched) with information that is of interest only to code that includes the rfkill.h header.

The resume handler should reset the wireless transmitter rfkill state to exactly what it was when the system was suspended. Do it, and do it using the normal routines for state change while at it. The suspend handler should force-switch the transmitter to blocked state, ignoring caches. Do it. Also take an opportunity shot to rfkill_remove_switch() and also force the transmitter to blocked state there, bypassing caches. Signed-off-by:

Unfortunately, instead of adding a generic Wireless WAN type, a technology- specific type (WiMAX) was added. That's useless for other WWAN devices, such as EDGE, UMTS, X-RTT and other such radios. Add a WWAN rfkill type for generic wireless WAN devices. No keys are added as most devices really want to use KEY_WLAN for WWAN control (in a cycle of none, WLAN, WWAN, WLAN+WWAN) and need no specific keycode added. Signed-off-by:

Currently, rfkill support for read/write rfkill switches is hacked through a round-trip over the input layer and rfkill-input to let a driver sync rfkill->state to hardware changes. This is buggy and sub-optimal. It causes real problems. It is best to think of the rfkill class as supporting only write-only switches at the moment. In order to implement the read/write functionality properly: Add a get_state() hook that is called by the class every time it needs to fetch the current state of the switch. Add a call to this hook every time the *current* state of the radio plays a role in a decision. Also add a force_state() method that can be used to forcefully syncronize the class' idea of the current state of the switch. This allows for a faster implementation of the read/write functionality, as a driver which get events on switch changes can avoid the need for a get_state() hook. If the get_state() hook is left as NULL, current behaviour is maintained, so this change is fully backwards compatible with the current rfkill drivers. For hardware that issues events when the rfkill state changes, leave get_state() NULL in the rfkill struct, set the initial state properly before registering with the rfkill class, and use the force_state() method in the driver to keep the rfkill interface up-to-date. get_state() can be called by the class from atomic context. It must not sleep. Signed-off-by:

Currently, radios are always enabled when their rfkill interface is registered. This is not optimal, the safest state for a radio is to be offline unless the user turns it on. Add a module parameter that causes all radios to be disabled when their rfkill interface is registered. The module default is not changed so unless the parameter is used, radios will still be forced to their enabled state when they are registered. The new rfkill module parameter is called "default_state". Signed-off-by:

rfkill really should have been named rfswitch. As it is, one can get confused whether RFKILL_STATE_ON means the KILL switch is on (and therefore, the radio is being *blocked* from operating), or whether it means the RADIO rf output is on. Clearly state that RFKILL_STATE_ON means the radio is *unblocked* from operating (i.e. there is no rf killing going on). Signed-off-by:

The TPA stands for Transparent Packet Aggregation. When enabled, the FW aggregate in-order TCP packets according to the 4-tuple match and sends 1 big packet to the driver. This packet is stored on an SGL in which each SGE is 1 page. The FW also implements a timeout algorithm and it honors all TCP flag, including the push flag as a trigger to halt aggregation. After receiving Ben Hutchings comments, we also added ethtool support, so now, thanks to Ben's patch, when forwarding is enabled, our aggregation is turned off using the LRO flags. Signed-off-by:

Supporting the 57711 and 57711E - refers to in the code as E1H. The 57710 is referred to as E1. To support the new members in the family, the bnx2x structure was divided to 3 parts: common, port and function. These changes caused some rearrangement in the bnx2x.h file. A set of accessories macros were added to make access to the bnx2x structure more readable Signed-off-by:

This new initialization code supports the 57711 HW. It also supports the emulation and FPGA for the 57711 and 57710 initializations values (very small amount of code which is very helpful in the lab - less than 30 lines). The initialization is done via DMAE after the DMAE block is ready - before it is ready, some of the initialization is done via PCI configuration transactions (referred to as indirect write). A mutex to protect the DMAE from being overlapped was added. There are few new registers which needs to be initialized by SW - the full comment for those registers is added to the register file. A place holder for the 57711 (referred to as E1H) microcode was added- the microcode itself is too big and it is split over the following 4 patches Signed-off-by:

New Link code: Moving all the link related code (including the calculations, the initialization of the MAC and PHY and the external PHY's code) into a separated file. The changes from the code that used to be part of bnx2x.c (now called bnx2x_main.c) are: - Using separate structures for link inputs and link outputs to clearly identify what was configured and what is the outcome - Adding code to read external PHY FW version and print it as part of ethtool -i - Adding code to upgrade external PHY FW from ethtool -E with special magic number - Changing the link down indication to ERR level - Adding a lock on all PHY access to prevent an interrupt and setting changes to overlap - Adding support for emulation and FPGA (small chunk of code that really helps in the lab) - Adding support for 1G on BCM8706 PHY - Adding clear debug print incase of fan failure (the PHY type is now "failure") Signed-off-by:

Use the same MSI-X handler to schedule NAPI. Change the dev_instance void pointer to the bnx2_napi struct instead so we can have the proper context for each MSI-X vector. Add a new bnx2_poll_msix() that is optimized for handling MSI-X NAPI polling of rx/tx work only. Remove the old bnx2_tx_poll() that is no longer needed. Each MSI-X vector handles 1 tx and 1 rx ring. The first vector handles link events as well. Signed-off-by:

Add hw_tx_cons_ptr and hw_rx_cons_ptr to speed up the retreival of the tx and rx consumer index, since the MSI-X and default status blocks have different structures. Combine status_blk and status_blk_msix into a union. We'll only use one type of status block for each vector. Separate the code to detect more rx and tx work from the code to detect link related work. Signed-off-by:
