* mwifiex: send firmware initialization commands synchronouslyStone Piao2012-09-281-32/+33
| | | | | | | | | | | | | | | | | The driver will send some commands to firmware during the initialization. Currently these commands are sent asynchronously, which means that we firstly insert all of them to a pre-allocated command queue, and then start to process them one by one. 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.

| | | | | | | | | | | | | | | | | | We need to have the promiscuous mode enabled for older chipsets so that the olderchips hardware does not filters out some valid/necessary frames that need to be sent to mac80211.

| * wlcore: protect wlcore_op_set_key with mutexEliad Peller2012-09-272-33/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

| * wlcore: Load the NVS file asynchronouslyIdo Yariv2012-09-272-38/+53
| | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

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).
