| | | | | | | | | | | | | | | | | | | | | | | | | | | | We make oldconfig every time when a new kernel arrives, but if we don't have such a device(I guess this is the most common case for a new device), the default value should be 'n' so that the kernel size we build doesn't grow up too much quickly. For anyone who has the device, it is OK for them to turn it on by themselves. Cc: "John W.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patch: rt2x00: Make rt2x00_queue_entry_for_each more flexible commit: 10e11568ca8b8a15f7478f6a4ceebabcbdba1018 introduced a severe regression on the throughput for USB hardware. It turns out that the exiting of the rt2x00queue_for_each_entry() was done too early. The exact cause for this regression is unknown, but by disabling the premature exiting of the loop seems to resolve the issue.

Instead we should set the diversity flag when possible, which will allow the link_tuner to automatically pick up the tuning.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Both USB and PCI drivers allow a system administrator to dynamically add USB/PCI IDs to the device table that a driver supports via the /sys/bus/{usb,pci,pci_express}/drivers/<driver-name>/new_id files. However, for the rt2x00 drivers using this method currently crashes the system with a NULL pointer failure. This is due to the set-up of rt2x00 where the probe functions require a rt2x00_ops structure in the driver_info field of the probed device. As this field is empty for the dynamically added devices this fails for these devices. Fix this by introducing driver-specific probe wrappers that do nothing but calling the bus-specific probe functions with the rt2x00_ops structure as an argument, rather than depending on the driver_info field.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When powersaving is enabled, assocaition times are very high (for WPA2 networks, the time can easily be around the 3 seconds). This is caused, because the flushing of the queues takes too much time. Without the flushing callback mac80211 assumes a timeout of 100ms while scanning. Limit all flush waiting loops to the same maximum. We can apply this maximum by passing the drop status to the driver, which makes sure the driver performs extra actions during the waiting for the queue to become empty. After these changes, association times fall within the healthy range of ~0.6 seconds with powersaving enabled. The difference between association time between powersaving enabled and disabled is now only ~0.1 second (which can also be due to the measuring method).

The TX_STA_FIFO is too small in hardware, thus reading it only from the workqueue is too slow and entries get lost. Start an asynchronous read of the TX_STA_FIFO directly from the TX URB completion callback (atomic context, thus it cannot use the blocking rt2800_register_read()). If the async read returns a valid FIFO entry, it is pushed into a larger FIFO inside struct rt2x00_dev, until rt2800_txdone() picks it up. A .tx_dma_done callback is added to struct rt2x00lib_ops to trigger the async read from the URB completion callback.

| * rt2x00: Split rt2x00dev->flagsIvo van Doorn2011-04-1919-153/+203
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The number of flags defined for the rt2x00dev->flags field, has been growing over the years. Currently we are approaching the maximum number of bits which are available in the field. A secondary problem, is that one part of the field are initialized only during boot, because the driver requirements are initialized or device requirements are loaded from the EEPROM. In both cases, the flags are fixed and will not change during device operation. The other flags are the device state, and will change frequently. So far this resulted in the fact that for some flags, the atomic bit accessors are used, while for the others the non-atomic variants are used. By splitting the flags up into a "flags" and "cap_flags" we can put all flags which are fixed inside "cap_flags". This field can then be read non-atomically. In the "flags" field we keep the device state, which is going to be read atomically. This adds more room for more flags in the future, and sanitizes the field access methods.

| * rt2x00: Enable WLAN LED on Ralink SoC (rt305x) devicesLayne Edwards2011-04-191-18/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds WLAN LED support to the mac80211 rt2x00 driver for Ralink SoC (rt305x) devices. The current WLAN LED drivers in rt2800lib.c set the LED brightness via an MCU request, but do nothing for SoC. This patch checks for SoC and sets the register to enable the WLAN LED (instead of an MCU request). This enables the WLAN LED for RT305x devices.

| * | rt2x00: Fix tx aggregation problems with some clientsHelmut Schaa2011-04-043-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some clients seem to rely upon the reception of BlockAckReqs to flush their rx reorder buffer. In order to fix aggregation for these clients rt2x00 should send a BlockAckReq if the transmission of an AMPDU subframe fails. Introduce a new flag TXDONE_AMPDU to indicate that this is an AMPDU subframe and pass IEEE80211_TX_STAT_AMPDU_NO_BACK to mac80211 if an AMPDU subframe failed during transmission. This fixes aggregation problems with Intel 5100 Windows STAs (and maybe others as well).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For STBC transmissions rt2x00 used the number of RxSTBC streams the destination STA indicates in its HT capabilities as STBC value in the TXWI. However, the legacy drivers and our own comment in rt2800.h suggest that the STBC field in the TXWI only allows a value of 0 or 1. The values 2 and 3 are reserved (probably for future devices). And indeed, STBC transmissions to STAs indicating more then 1 RxSTBC stream fail when the STBC field is set to something >1. Fix this by only setting the STBC field to 1 when STBC should be used.

| * | rt2x00: Implement tx power temperature compensationHelmut Schaa2011-04-049-5/+296
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | rt2800 devices should adjust their tx power in accordance with the eeproms temperature calibration values. Add a new driver callback gain_calibration that is called every 4 seconds. The rt2800 gain calibration routine simply runs the tx power configuration that takes care of calculating the temperature compensation delta. We don't need to synchronize the calls to rt2800_config_txpower as they should all happen from mac80211's single threaded workqueue.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit d1c3a37ceeb1a5ea02991a0476355f1a1d3b3e83 ("mac80211: clarify alignment docs, fix up alignment") removed the requirement for a 4-byte aligned payload rt2x00queue_align_payload is obsolete as mac80211 will align the payload when it passes the frame to the net stack. As a result we can remove the call to rt2x00queue_align_payload in the rx path and since that's the last user we can remove rt2x00queue_align_payload altogether. One advantage is that we save some alignment operations for frames that don't need to be aligned (for example beause they are not passed to the net stack).
