2009-08-14rt2x00: Fix beacon de-synchronization while update beaconIgor Perminov
When beacon is being updated to refresh TIM (AP mode), beacon frames are de-synchronizing (i.e. two neighbor beacon frames - before and after update - are being transmitted with a wrong time interval). That is because xxx_write_beacon should disable beacon generation only while beacon data are being uploaded to the device, but it should not disable the beacon clock.

This patch implements FIF_PSPOLL filter flag support in rt2x00 drivers, which has been introduced in mac80211 (see http://marc.info/?l=linux-wireless&m=124897986330807&w=2).

2009-08-04rt61pci: fix module reloadingPavel Roskin
Unloading rt61pci can leave the device in such state that reloading rt61pci would fail to reinitialize it. Bogus data would be read from the EEPROM and the RF version won't be recognized. It appears that unloading rt61pci with power saving enabled would have such effect. To initialize the device properly, SOFT_RESET_CSR should be set to the same value as rt61pci_config_ps() uses to wake up the device.

2009-07-24rt2x00: Implement set_tim callback for all driversStefan Steuerwald
Implement set_tim callback for all rt2x00 drivers, this makes the device wake up powersaving stations properly while in AP mode. The only way to update the beacon is by simply calling mac80211 and requesting the new beacon. This means the set_tim() event is mostly the same as a beacon_done() event which was already defined in rt2x00lib.

2009-07-10rt2x00: use wiphy rfkill interfaceIvo van Doorn
Remove the input_polldev from rt2x00 and replace it with the rfkill interface offered by the wiphy structure. This simplifies the entire rfkill handling in rt2x00 and allows us to remove the CONFIG_RT2X00_LIB_RFKILL option and always enables rfkill capabilities.

2009-06-03rt2x00: Remove last usage of beacon_int from ieee80211_configIvo van Doorn
This removes the last usage of beacon_int inside the iee80211_config structure from rt2x00. The attempt is a bit hackish, and subject to change in the future when the entire rt2x00_dev structure is cleaned up and restructured.

2009-05-06mac80211: unify config_interface and bss_info_changedJohannes Berg
The config_interface method is a little strange, it contains the BSSID and beacon updates, while bss_info_changed contains most other BSS information for each interface.

2009-04-22rt2x00: Move Move pci_dev specific access to rt2x00pciIvo van Doorn
pci_dev->irq and pci_name(pci_dev) access should be limited to rt2x00pci only. This is more generic and allows a rt2x00 pci driver to be controlled as PCI device but also as platform driver (needed for rt2800pci SoC support).

2009-02-27rt2x00: Remove check for rf word 0Ivo van Doorn
The only way rf_write() can be called with word 0 is when the user sends the wrong word index through debugfs. However the values which are send through debugfs are validated using the RF_BASE and RF_SIZE macro values, the most logical solution is to increase RF_BASE with 4 and decrease RF_SIZE with 4 (RF_SIZE has always been 1 word too big) Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

2009-02-09rt2x00: Validate firmware in driverIvo van Doorn
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.

2009-02-09rt2x00: Add kill_tx_queue callback functionIvo van Doorn
provide rt2x00lib the possibility to kill a particular TX queue.

2009-01-29rt2x00: Restrict interface between rt2x00link and driversIvo van Doorn
Restrict drivers to only access link_qual structure during link tuning. The contents of these fields are for the drivers and all fields are allowed to be changed to values the driver considers correct. This means that some fields need to be moved outside of this structure to restrict access only to rt2x00link itself. This allows some code to be moved outside of the rt2x00.h header and into rt2x00link.c. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2009-01-29rt2x00: Reduce calls to bbp_read()Ivo van Doorn
The link_tuner() function will always call bbp_read() at the start of the function. Because this is an indirect register access has some costs attached to it (especially for USB hardware). We already store the value read from the register into the vgc_level value inside the link structure. Instead of reading from the register we can read that field directly and base the tuner on that value. This reduces the time the registers are locked with the csr_mutex and speeds up the link_tuner processing. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

2008-12-05rt2x00: Optimize IV/EIV handlingIvo van Doorn
IV and EIV belong to eachother and don't require 2 seperate fields. Instead they can logically be merged into a single array with size 2. With this approach we can simplify the code in rt2x00crypto.c by using a single memcpy() when copying the iv/eiv data. Additionally we can move some code out of if-statements because the if-statement would always be true. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

2008-11-25rt2x00: Cleanup indirect register accessIvo van Doorn
All code which accessed indirect registers was similar in respect to the for-loop, the given timeout, etc. Move it into a seperate function, which for PCI drivers can be moved into rt2x00pci. This allows us to cleanup the cleanup the code further by removing the goto statementsand making the codepath look a bit nicer. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

2008-11-21rt2x00: Fix race condition when using inderect registersIvo van Doorn
Indirect registers require multiple calls to the CSR register in order to access the indirect registers. This must be protected under a lock to prevent race conditions which could cause invalid data to be returned when reading from the indirect register or silent failures when writing data to the indirect register. USB drivers where already protected under a mutex, so rename the mutex and make PCI drivers use the mutex as well. This now means that BBP and RF registers are no longer accessible in interrupt context. That is not a bad situation since the slow behavior of accessing those registers means we don't _want_ to access them in interrupt context either.

2008-11-21rt2x00: Cleanup TX/RX entry handlingIvo van Doorn
Merge the callback functions init_txentry() and init_rxentry(). This makes life in rt2x00lib a lot simpler and we can cleanup several functions. rt2x00pci contained "fake" FIELD definitions for descriptor words. This is not flexible since it assumes the driver will always have the same field to indicate if a driver is available or not. This should be dependent on the driver, and we should add a callback function for this. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2008-09-24rt2x00: Fix HW crypto key handlingIvo van Doorn
When a crypto key is being removed, rt2x00mac should not reset the key->hw_key_idx value because that will prevent the driver from removing the correct key from the hardware.

RFKILL should be enabled for _all_ hardware whether or not they feature a rfkill button or not. Remove driver specific RFKILL configuration options and make the rt2x00lib version depend on CONFIG_RFKILL and defaulting to 'y' to make sure it will always be enabled when RFKILL was enabled.

2008-08-29rt2x00: Fix race conditions in flag handlingIvo van Doorn
Some of the flags should be accessed atomically to prevent race conditions. The flags that are most important are those that can change often and indicate the actual state of the device, queue or queue entry. The big flag rename was done to move all state flags to the same naming type as the other rt2x00dev flags and made sure all places where the flags were used were changed. ;) Thanks to Stephen for most of the queue flags updates, which fixes some of the most obvious consequences of the race conditions. Among those the notorious: rt2x00queue_write_tx_frame: Error - Arrived at non-free entry in the non-full queue 0. rt2x00queue_write_tx_frame: Error - Arrived at non-free entry in the non-full queue 0. rt2x00queue_write_tx_frame: Error - Arrived at non-free entry in the non-full queue 0.

2008-08-22rt2x00: Move lna_gain calculation to config() callbackIvo van Doorn
We can optimize lna calculation in IRQ context by calculating most of the value during the config() callback when most of the value is actually influenced.
