2012-07-10brcmsmac: remove PCI_FORCEHT() macroHauke Mehrtens
The BCM4716 is a SoC and does not have a PCI client interface, so this condition is never true. Acked-by: Arend van Spriel <arend@broadcom.com> Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2012-07-10brcmsmac: remove PCIE() macroHauke Mehrtens
Instead of checking if there is a PCIe core on the bus, better check if hosttype is PCIe. In the original submission to staging PCIE() checked, if the bustype is PCI and the buscore is a PCIe core. Now we assume that all cores bcma supports are PCIe based, so we just have to check if the bustype is PCI. The old code bcmsmac currently uses searches for a PCIe core on the bus and if there is one assumes that this is the buscore, which is wrong. Some SoCs have a PCIe core operating in host mode and this is not the bus core. The old code also caused a null pointer in ai_get_buscoretype() and ai_get_buscorerev() if buscore was not set because there was no PCIe core on the bus.

2012-07-10wlcore: determine AP extra rates correctlyArik Nemtsov
Don't use the ht_mode module parameter for determining AP supported rates. We can rely on channel type, since HT40 won't be enabled if our HT cap doesn't support it. Enable MIMO only if there enough antennas, and rely on per-peer rate limitation to prevent IOPs. Signed-off-by: Arik Nemtsov <arik@wizery.com>
2012-07-10wlcore: check ssid length against the correct elementEliad Peller
commit 587cc28 ("wlcore: compare ssid_len before comparing ssids") introduced a new bug - the ssid length from the request struct was compared against the ssid length of another request, instead the one of the cmd. This might cause the sched scan request to fail (with -EINVAL) in many cases. Signed-off-by: Eliad Peller <eliad@wizery.com>
2012-07-10wl12xx/wl18xx: use a dynamic PS timeout of 1.5secArik Nemtsov
It seems some parties have bad user experience when smaller values are used. This should have little implications for power consumption, since traffic is bursty in nature. Signed-off-by: Arik Nemtsov <arik@wizery.com>
2012-07-10wlcore: define number of supported bands internallyArik Nemtsov
Avoid using the IEEE80211_NUM_BANDS constant for arrays sizes etc, as this can contain bands unsupported by the driver (e.g. 60Ghz). Use an internal constant to determine the number of bands. Signed-off-by: Arik Nemtsov <arik@wizery.com>
2012-07-10wlcore: don't set SDIO_FAILED flag when driver state is offArik Nemtsov
If some IO read/write fails while the FW is not loaded, a recovery will not take place. This means the SDIO_FAILED flag will stay in place forever and prevent further read/writes. This can happen if a check for STATE_OFF was forgotten in some routine. Take this opportunity to rename the flag to IO_FAILED, since we support other buses as well.

2012-07-10wlcore: change the wait for event mechanismYoni Divinsky
wlcore needs to wait for certain events for example for roc complete event. Usually the events are received from the FW very fast, therefore wlcore can poll with a short delay and if after a second the event was not received yet poll with a long (1-5 msec) delay. This implementation is similar to the sending of commands to the FW. Empirically the change reduced the wait for roc event from ~10-40msec to 100s of usecs.

2012-07-10wlcore: Prevent processing of work items during op_stopIdo Yariv
The interrupt line is disabled in op_stop using disable_irq. Since pending interrupts are synchronized, the mutex has to be released before disabling the interrupt to avoid a deadlock with the interrupt handler. In addition, the internal state of the driver is only set to 'off' after the interrupt is disabled. Otherwise, if an interrupt fires after the state is set but before the interrupt line is disabled, the interrupt handler will not be able to acknowledge the interrupt resulting in an interrupt storm. The driver's operations might be called during recovery. If these acquire the mutex after it was released by op_stop, but before the driver's state is changed, they may queue new work items instead of just failing. This is especially problematic in the case of scans, in which a new scan may be scheduled after all scan requests were cancelled.

2012-07-10wl12xx/wlcore: increase FW filename versionLuciano Coelho
We have some API changes and new features in the new firmwares that are not compatible with older drivers. Increase the version of the FW filenames for wl12xx to 5. Additionally, remove the duplicate definitions from wlcore_i.h and remove the MODULE_FIRMWARE macro calls from the SDIO and SPI modules, since they're irrelevant there. Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-07-10wlcore: add probe request templates for sched and one-shot scansYoni Divinsky
The driver configures the firmware template for probe requests during the scan process. If the same template is used for one-shot and sched scans they will override each other when running scans simultaneously. This fix works only on firmwares later than X.3.9.2.112 for single role and X.3.9.2.23 for multi-role.

2012-07-10wlcore: always clear recovery flag during recovery_workArik Nemtsov

2012-07-10wlcore: avoid debug prints during intended FW recoveryArik Nemtsov

2012-07-10wlcore: remove recover cmd from testmodeArik Nemtsov

2012-07-10wlcore: enable sched scan while connectedVictor Goldenshtein
New wl12xx firmware supports scheduled scans also while connected. Stop blocking sched scan requests when connected and add a quirk to block in hardware that don't support it (currently wl18xx doesn't).

2012-07-09ath9k: Stop the BTCOEX timers before disabling BTCOEXMohammed Shafi Shajakhan
Its safe to stop the BTCOEX timers 'period_timer' and 'no_stomp_timer' before disabling BTCOEX. These timers can call ath9k_hw_btcoex_enable (or) change the BT stomp type if they seem to be running after we had called ath9k_hw_btcoex_disable, which is obviously not correct.
