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.

2009-05-22rt2x00: Remove usage of IEEE80211_CONF_CHANGE_BEACON_INTERVALIvo van Doorn
IEEE80211_CONF_CHANGE_BEACON_INTERVAL was deprecated a month ago, it is about time to remove all usage from the rt2x00 drivers and use the correct beacon interval configuration through the bss_info structure.

rt2x00_check_rev() was too specific for rt2500usb and rt73usb, by adding the mask argument (instead of hardcoding it into the function itself) we can use the function in rt2800usb as well. v2: Fix revision mask for rt2800usb Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

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. This patch removes config_interface and rolls all the information it previously passed to drivers into bss_info_changed.

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.

2009-01-29rt2x00: 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>

2009-01-12rt2x00: Fix rt2500usb HW crypto: WEP 128 & AESIvo van Doorn
The TXD_W0_CIPHER field is a 1-bit field. It only acts as boolean value to indicate if the frame must be encrypted or not. The way rt2x00_set_field32() worked it would grab the least signifcant bit from txdesc->cipher and use that as value. Because of that WEP 64 and TKIP worked since they had odd-numbered values, while WEP 128 and AES were even numbers and didn't work. Correctly booleanize the txdecs->cipher value to allow the hardware to encrypt the outgoing data. After this we can enable HW crypto by default again.

2009-01-12Fix rt2500usb HW crypto: TKIPIvo van Doorn
rt2500usb doesn't strip the IV/ICV data from received frames, so we don't need to set the RX_FLAG_IV_STRIPPED flag. We do need to set the RX_FLAG_MMIC_STRIPPED flag for all encryption types since the MMIC has been removed from the frame. After this patch TKIP Hardware crypto works for rt2500usb.

2008-11-25rt2x00: Detect USB BULK in/out endpointsIvo van Doorn
Instead of hardcoding the used in/out endpoints we should detect them by walking through all available endpoints. rt2800usb will gain the most out of this, because the legacy drivers indicate that there are multiple endpoints available. However this code might benefit at least rt73usb as well for the MIMO queues, and if we are really lucky rt2500usb will benefit because for the TX and PRIO queues. Even if rt2500usb and rt73usb do not get better performance after this patch, the endpoint detection still belongs to rt2x00usb, and it shouldn't hurt to always try to detect the available endpoints.

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. Linville <linville@tuxdriver.com>
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: Optimize get_duration / get_duration_resIvo van Doorn
We can optimize get_duration and get_duration_res by making them a macro. They are really simple calculation handlers so this doesn't matter much. Often (especially in rt2400pci and rt2500pci, the arguments are hardcoded, and the result value is passed into other hardcoded values. By making the functions a macro GCC can optimize the entire thing much better. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
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>
2008-11-10rt2x00: Remove debugfs CSR access wrappersIvo van Doorn

2008-11-10rt2x00: Optimize configuration handlingIvo van Doorn

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.

In the legacy rt2570 driver the link tuner was never really called. And now the reason has finally become apparent: It breaks TX capabilities As soon as the device has been associated all following TX frames will be queued in the hardware and never transmitted to the air. Disabling sections of the link tuner did not have the expected result, but completely disabling the link tuner did have the right result (Both of my rt2570 devices came back to life).

2008-07-29rt2x00: Fix the beacon length bugIwo Mergler
When setting up a beacon template, the length of the beacon is calculated with the assumption that the SKB already contains the Tx descriptor. In the case of beacons it doesn't. This patch undoes the damage by adding the Tx descriptor length to the beacon length. This is safe, because the shortest possible beacon is longer than the Tx header.

This patch changes mac80211's beacon configuration handling to never pass skbs to the driver directly but rather always require the driver to use ieee80211_beacon_get(). Additionally, it introduces "change flags" on the config_interface() call to enable drivers to figure out what is changing.

2008-07-09rt2x00: Disable synchronization during initializationIvo van Doorn
As soon as init_registers() was called, the rt2400/rt2500 would start raising beacondone interrupts. Since this is highly premature since no beacons were provided yet, we should initialize the synchronization register to 0. This will make all drivers initialize it to 0 regardless if they are raising beacondone interrupts or not, since it only makes sense to have it completely disabled.
