The recent rt2800 devices are no longer really identified by their PCI ID's, but rather by the contents of their CSR0 register. Also for the other chipsets is the contents of this CSR0 register important. Change the chipset determination logic to be more aligned with the rt2800 model.

We've had many reports of rt61pci failures with powersaving enabled. Therefore, as a stop-gap measure, disable powersaving of the rt61pci until we have found a proper solution.

Some drivers (rt2800* most notably) cannot set the RF and RT chipset in the correct order to have the information logging in rt2x00_set_chip be correct.

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.

2009-09-09rt2x00: Hardcode TX ack timeout and consume timeIvo van Doorn
The calculated values for the ACK timeout and ACK consume time are different then the values as used by the Legacy drivers. After testing from James Ledwith it appeared that the calculated values caused a high amount of TX failures, and the values from the Legacy drivers were the most optimal to prevent TX failure due to excessive retries. The symptoms of this problem: - Rate control module always falls back to 1Mbs - Low throughput when bitrate was fixed Possible side-effects (not confirmed but highly likely) - Problems with DHCP - Broken connections due to lack of probe response This should fix at least: Kernel bugzilla reports: [13362], [13009], [9273] Fedora bugzilla reports: [443203] but possible some additional bugs as well.

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.

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.

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.

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.

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: 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>
