2012-09-27wlcore: AP mode - send non-data packets with basic ratesArik Nemtsov
This solves interoperability issues with peer that don't seem to "hear" management packets transmitted in higher rates. Based on a previous patch by Igal Chernobelsky. Cc: Igal Chernobelsky <igalc@ti.com> Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <luca@coelho.fi>
2012-09-27wlcore: cancel recovery_work on stop() instead of remove_interface()Eliad Peller
recovery_work should be cancelled when stopping the device, not when removing an interface (this is probably a leftover from the single-role days) Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <luca@coelho.fi>

2012-09-27wlcore: Prevent interaction with HW after recovery is queuedIdo Yariv
When a function requests to recover, it would normally abort and will not send any additional commands to the HW. However, other threads may not be aware of the failure and could try to communicate with the HW after a recovery was queued, but before the recovery work began. Fix this by introducing an intermediate state which is set when recovery is queued, and modify all state checks accordingly.

2012-09-27wlcore: consider single fw caseEliad Peller
When a single fw is being used for both single-role and multi-role cases (e.g. 18xx), wl->mr_fw_name is NULL, which results in NULL dereference while trying to load the multi-role fw. In this case, always use the single-role fw, and avoid redundant fw switch by checking for this case in wl12xx_need_fw_change() as well.

2012-09-27wl18xx: update default phy configuration for pg2Ido Reis

Declare any firmware that might be used by this driver. If all drivers declare their firmware usage, then a sufficiently complete list of firmware files can then be used to pare down the external linux-firmware package to just the files in actual use.

Remove the control.sta pointer from ieee80211_tx_info to free up sufficient space in the TX skb control buffer for the upcoming Transmit Power Control (TPC).

2012-07-18wlcore: increase command completion timeoutLuciano Coelho

2012-07-18wlcore: wait for command completion event when sending CMD_ROLE_STOPLuciano Coelho
We need to wait for the command completion event when we send the CMD_ROLE_STOP event otherwise we may try to send CMD_ROLE_START too soon and get out-of-sync with the firmware. In some cases, the firmware may not send the event, so we wait for the event or for the timeout, whichever comes first. This patch is based on an earlier version by Eliad.

2012-07-18wlcore: make usage of nla_put clearerYair Shapira
handle errors of nla_put() inside the if(nla_put...) {} This makes the code simpler and clearer because: we take advantage from the fact that we have only one nla_put in our routines (so no real need for goto label). this avoids ugly goto forward followed by goto backward.

2012-07-18wlcore: add plt_mode including new PLT_FEM_DETECTYair Shapira
add wl->plt_mode that is used to indicate different plt working modes: this will be used to implement calibrator side auto fem detection where driver asks firmware to detect the wlan fem radio type and returns it to calibrator. this is not implemented yet and plt_modes: PLT_ON and PLT_FEM_DETECT currently behave the same.

2012-07-18wlcore: use basic rates for non-data packetsEliad Peller
After the latest mac80211 changes, the sta has the ap's sta pointer even before association. This cause the auth and assoc frames to be sent with the standard ap's rates, rather than the basic rates. Change the tx rate policy logic to use the regular ap rates only for data packets (so control and mgmt packets will be sent with basic rates) Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-07-18wlcore: don't issue SLEEP_AUTH command during recoveryArik Nemtsov

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: avoid debug prints during intended FW recoveryArik Nemtsov
