* rt2x00: Update copyright statements.Gertjan van Wingerde2009-11-111-1/+1
| | | | | | | | | | | | | | | | As mentioned on the linux-wireless mailing list, the current copyright statements in the rt2x00 are meaningless, as the rt2x00 project is not even a formal legal entity. Therefore it is better to replace the existing copyright statements with copyright statements for the people that actually wrote the code. Note: Updated to the best of my knowledge with respect to who contributed considerable amounts of code.

* rt2x00: Validate firmware in driverIvo van Doorn2009-02-091-0/+10
| | | | | | | | | | | | | The get_firmware_crc() callback function isn't flexible enough when dealing with multiple firmware versions. It might in some cases be possible that the firmware file contains multiple CRC checksums. Create the check_firmware() callback function where the driver has complete freedom in how to validate the firmware. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

* rt2x00: Remove ENTRY_TXD_OFDM_RATEIvo van Doorn2009-01-291-0/+10
| | | | | | | | | | | | | The flag ENTRY_TXD_OFDM_RATE isn't flexible enough to indicate which rate modulation should be used for a frame. This will become a problem when 11n support is added. Remove the flag and replace it with an enum value which can better indicate the exact rate modulation. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A "Set" to a sign-bit in an "&" operation causes a compiler warning. Make calculations unsigned. [ The warning was masked by the old definition of BUILD_BUG_ON() ] Also remove __builtin_constant_p from FIELD_CHECK since BUILD_BUG_ON no longer permits non-const values.

* | rt2x00: Implement HW encryptionIvo van Doorn2008-08-221-1/+18
|/ | | | | | | | | | | | | | | Various rt2x00 devices support hardware encryption. Most of them require the IV/EIV to be generated by mac80211, but require it to be provided seperately instead of within the frame itself. This means that rt2x00lib should extract the data from the frame and place it in the frame descriptor. During RX the IV/EIV is provided in the descriptor by the hardware which means that it should be inserted into the frame by rt2x00lib.

* rt2x00: Use __builtin_choose_expr() instead of ?:Ivo van Doorn2008-06-141-9/+13
| | | | | | | | | To really force the FIELD macros to determine the first bit of the register field we should use the __builtin_choose_expr() function. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* rt2x00: Make rt2x00_set/get_field macrosIvo van Doorn2008-06-141-41/+30
| | | | | | | | | | | | The rt2x00_set_field functions are very often used, but GCC is better able to optimize them when they are macros instead of static inline functions. After changing it to macro's each rt2x00 driver will loose about ~3500 bytes in size. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* rt2x00: Calculate register offset during compile timeIvo van Doorn2008-06-141-14/+45
| | | | | | | | | | | | | | | | | | | | | By using __ffs() the register offsets were always calculated at run-time which all FIELD32/FIELD16 definitions were builtin constants. This means we can heavily optimize the register handling by allowing GCC to do all the work during compilation. Add some compile_ffs() macros to perform the calculation at compile time. After this each rt2x00 module size is reduced by ~2500 bytes. And the stack size of several functions is reduced as well which further limits the number of rt2x00 results in 'make checkstack'. v2: Merge GertJan's bugfix of patch [1/11] directly into this patch       instead of providing it as seperate patch. v3: Add extra parentheses when bitshifting __x Signed-off-by: Gertjan van Wingerde <gwingerde@kpnplanet.nl> Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

* rt2x00: Fix TX status reportingIvo van Doorn2008-05-211-11/+0
| | | | | | | | | | | | | | | | | | | | | The tx_status enumeration was broken since the introduction of rt61pci. That driver uses different values to report the status of the tx action. This would lead to frames that were reported as success but actually failed to be send out, or frames that were neither successfull or failure which were reported as failure. Fix this by change the TX status reporting and more explicitely check for failure or success. Note that a third possibility is added "unknown". Not all hardware (USB) can report the actual TX status, for rt61pci some frames will receive this status because the TXdone handler is never called for those frames. This unknown will now be handled as neither success or failure, so we no longer increment the failure counter while this conclusion could not be determined from the real status of the frame.

* rt2x00: Rate structure overhaulIvo van Doorn2008-02-291-71/+0
| | | | | | | | | | | | | | Recent changes to the rate structure registration broke rt2x00, the hw_value was reduced from 32bits to 16bits while rt2x00 used the full 32bits. However the way rt2x00 used the value was inflexible and needed to be changed anyway. This patch creates a array containing information for each rate, the hw_value passed to mac80211 is the index value for that array including a field to indicate if short preamble should be enabled.

* rt2x00: Queue handling overhaulIvo van Doorn2008-02-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This introduces a big queue handling overhaul, this also renames "ring" to "queues". Move queue handling into rt2x00queue.c and the matching header, use Kerneldoc to improve rt2x00 library documentation. Access to the queues is now protected under a spinlock, this to prevent race conditions which could corrupt the indexing system of the queue. Each queue entry allocates x bytes for driver/device specific data, this cleans up the queue structure significantly and improves code readability. rt2500usb no longer needs 2 entries in the beacon queue to correctly send out the guardian byte. This is now handled in the entry specific structure. rt61 and rt73 now use the correct descriptor size for beacon frames, since this data is written into the registers not the entire TXD descriptor was used but instead of a subset of it named TXINFO. Finally this also fixes numerous other bugs related to incorrect beacon handling or beacon related code. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

* rt2x00: Add link tuner safe RX toggle statesIvo van Doorn2008-02-281-0/+2
| | | | | | | | | | | | | This adds 2 new states which both are used to toggle the RX. These new states are required for usage inside the link tuner thread, because the normal RX toggling will stop the link tuner thread. While it is possible that the link tuner thread itself is the caller of the RX toggle (when using software antenna diversity). Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.
