git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next John W. Linville says: ==================== Here is another batch of updates intended for 3.7... Highlights include an hci_connect re-write in Bluetooth, HCI/LLC layer separation in NFC, removal of the raw pn544 NFC driver, NFC LLCP raw sockets support, improved IBSS auth frame handling in mac80211, full-MAC AP mode notification support in mac80211, a lot of attention paid to brcmfmac, and the usual level of updates to iwlwifi, ath9k, mwifiex, and rt2x00, and various other updates. ==================== Signed-off-by: David S.

2012-09-28ath9k: Fix BTCOEX weight initializationSujith Manoharan
The WLAN/BT weights have to set correctly before BTCOEX is initialized. Currently, this is not done for all chips in the AR9003 family. This patch fixes this issue by setting the weights in the init path. While at it, rename ar9462_wlan_weights to mci_wlan_weights since it is common to both AR9462 and AR9565.

2012-09-28mwifiex: send firmware initialization commands synchronouslyStone Piao
The driver will send some commands to firmware during the initialization.

The command queue will soon be exhausted if we keep adding new initialization commands. This issue can be resolved by sending initialization commands synchronously because each command is consumed and the buffer is recycled before queuing next command.

2012-09-27wlcore: protect wlcore_op_set_key with mutexEliad Peller
wlcore_op_set_key() calls wl18xx_set_key(), which in turn executes some of his function calls without acquiring wl->mutex and making sure the fw is awake. Adding mutex_lock()/ps_elp_wakeup() calls is not enough, as wl18xx_set_key() calls wl1271_tx_flush() which can't be called while the mutex is taken. Add the required calls to wlcore_op_set_key, but limit the queues_stop and flushing to the only encryption types in which a spare block might be needed (GEM and TKIP).

2012-09-27wlcore: decrease elp timeoutEliad Peller
The current elp timeout (the same as the dynamic ps timeout - 1500ms) is too high. Usually, wl1271_ps_elp_sleep() get called right after tx/rx, which is fine, but some command might get sent even when there is no traffic (e.g. ht changes triggered by beacon frames), and leaving the device awake for 1500ms in this case is redundant. Use a timeout of 30ms. The fw won't enter elp anyway before the dynamic-ps timeout was expired as well (and it entered ps successfully).

2012-09-27wlcore: Load the NVS file asynchronouslyIdo Yariv
The NVS file is loaded by the device's probe callback with the help of request_firmware(). Since request_firmware() relies on udevd, the modules cannot be loaded before hotplug events are handled. Fix this by loading the NVS file asynchronously and continue initialization only after the firmware request is over.

2012-09-27wlcore: Refactor probeIdo Yariv
Move most of the device-specific probe functionality into setup(), a new op. By doing this, wlcore_probe will be the first to request a firmware from userspace, making it easier to load the NVS file asynchronously.

2012-09-27wlcore: Allow memory access when the FW crashesIdo Yariv
When the no_recovery flag is used, the recovery work will not restart the FW and the state will not be set to 'on'. To enable post-mortem analysis, allow memory access in the 'restarting' state. Also, since the FW might not be operational, don't fail the read/write operations if elp_wakeup fails.

2012-09-27wlcore: use dynamic keep-alive template idsEliad Peller
Currently, all the (station) roles use the same keep-alive template id (0). However, the klv template ids shouldn't be shared by different roles. Implement a simple klv_templates bitmap, and let each role allocate its own klv template id on role initialization. [Arik - remove invalidation of KLV template when getting into "idle". This is already handled in unjoin] Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <luca@coelho.fi>
2012-09-27wlcore: invalidate keep-alive template on disconnectionEliad Peller
Previously, invalidation of the keep-alive template was done when going idle. However, while removing the idle-handling we didn't move the keep-alive template invalidation to another place. This finally resulted in fw error when trying to use the keep-alive template by another role. (Note that we still have an error here - each role should have its unique keep-alive template id, while currently they all use CMD_TEMPL_KLV_IDX_NULL_DATA (0). This only works now because we don't support concurrent connected stations yet) Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <luca@coelho.fi>

2012-09-27wlcore: Fix unbalanced interrupts enablementIdo Yariv

2012-09-27wlcore: Don't recover during bootIdo Yariv
While recursive recovery is avoided during shutdown, a new recovery may be queued when the FW boots. The recovery work will then try to stop an already stopped hardware, which will most likely result in a kernel panic. Fix this by verifying that wl->state is on before queueing a new recovery.
