2012-07-17mwifiex: improvement in cfg80211 set_bitrate_mask handlerAmitkumar Karwar
This patch configures data rates to firmware using bitrate mask provided by cfg80211. Earlier we used to only update band information in this handler which will be used later for ibss network. Due to recent modifications in ibss join code we don't need to do that.

2012-07-17mwifiex: remove unnecessary code in data rate configurationAmitkumar Karwar
1) Remove unnecessary wrapper functions. 2) Currently we don't have command to set Tx data rate, so mwifiex_rate_ioctl_set_rate_value() function and related code can be removed. 3) "ds_rate" filled by mwifiex_ret_tx_rate_cfg() is never used.

2012-07-17mwifiex: remove redundant code in set channel pathAmitkumar Karwar
1) Recently we removed set_channel cfg80211 handler. Also, cfg80211 blocks ibss connection requests if ibss network is already started /joined. Hence the code to restart ibss network in new channel (mwifiex_drv_change_adhoc_chan() function) becomes redundant. 2) mwifiex_bss_set_channel() function is redundant. It does some error checking and calculate adhoc start band and adhoc channel. Cfg80211 already takes care of error checking and provides correct channel information to the driver. Adhoc start band is already calculated in mwifiex_set_rf_channel() function. Other associated code is also removed in this patch.

2012-06-28mwifiex: wakeup main thread to handle command queuedAmitkumar Karwar
We miss to wakeup main thread after adding command to cmd pending queue at follwing places. These commands are handled later when main thread is woken up for handling an interrupt for sleep event from firmware. This adds worst case delay of 50msec. 1) We don't wakeup main thread when asynchronous command is added to cmd pending queue. Move queue_work() call from mwifiex_wait_queue_complete() to mwifiex_send_cmd_async() to wakeup main thread for sync as well as async commands. 2) Scan operation is triggered due to following reasons a) request from user (ex. "iw scan" command) b) Scan performed by driver internally. In first case main thread is woken up when first scan command is queued in cmd pending queue (we don't need to wakeup main thread for subsequent scan commands, because they are queued in scan command response handler), but it is not done for second case. queue_work() is moved inside mwifiex_scan_networks() to handle both the cases.

2012-06-11mwifiex: fix simultaneous scan and Tx traffic problemAmitkumar Karwar
If scan operation is started when Tx traffic is already running, driver locks Tx queue until it gets completed. With this logic there is a delay for Tx packets. This patch implements new approach to give Tx path higher priority in this case. Driver internally sends multiple synchronous scan commands to firmware when scan is requested by user. Now we will make sure that Tx queue is empty everytime before sending next scan command. If Tx queue isn't empty scan command will be postponsed by 20msec. This rule will be followed until Tx queue becomes empty or timeout of 1 second happens. In case of timeout scan operation will be aborted.

2012-04-17mwifiex: corrections in timestamp related codeAmitkumar Karwar
We get two timing related fields for each bss from firmware in scan results. 1) timestamp - Actual timestamp information in probe response/beacon 2) network_tsf - firmware's TSF value at the time the beacon or probe response was received. Both are needed while associating by firmware. The patch takes care of following things. 1) We should pass "timestamp" to cfg80211_inform_bss(), but currently "network_tsf" is being provided. This error is corrected here. 2) Rename "network_tsf" to "fw_tsf" 3) Make use of u64 variable instead of an array of u8/u32 to save parsed "timestamp" information. 4) Use timestamp provided to stack in scan results using cfg80211_inform_bss() while associating. (bss->tsf) 5) Allocate space to save fw_tsf in "priv" of cfg80211_bss and retrieve it while associating.

IEEE80211_MAX_QUEUES is an internal mac80211 value, it is not guaranteed to be always 4. The firmware API in mwifiex almost certainly doesn't care about mac80211 changing though, so mwifiex shouldn't use this value.

Currently due to following issues in the code even if device is configured in B only, G only or BG mode using iw bitrates command, ibss is getting created in BGN mode. 1) mwifiex_channels_to_cfg80211_channel_type() routine gives channel type as NL80211_CHAN_HT20 for non-HT channel as well, because driver doesn't store HT information provided by stack for the channel.

2011-10-14mwifiex: use separate wait condition for each command nodeAmitkumar Karwar
Currently global wait condition (adapter->cmd_wait_q.condition) is used while sending synchronous commands to FW. When two threads enter in mwifiex_send_cmd_sync() routine at the same time, both the threads wait for their command responses. Since wait condition is same for both, they wake up simultaneously after getting response of 1st command. After this when a thread is waiting for command response of 3rd command, it wakes up after getting response of 2nd command and so on. Therefore we don't wait for the response of last command(0xaa) during unload. Hence while next time loading the driver command time out is seen for INIT command. This problem is resolved by having separate wait condition flag for each command(except scan command). Since scan command is treated differently (by maintaining scan pending q etc.), newly defined flag (scan_wait_q_woken) is used as a scan wait condition.
