2012-10-24mwifiex: return -EBUSY if specific scan request cannot be honoredBing Zhao
Previous patch "mwifiex: return -EBUSY if scan request cannot.." corrected regular scan request only. There is another case for specific scan that needs the same handling. Also, removed !req_ssid check as it has already been validated by caller.

2012-10-08mwifiex: update cfg80211 with correct reason code when connection is lostAmitkumar Karwar
Driver gets LINK_LOST, DEAUTHENTICATED and DISASSOCIATED events from firmware when connection is lost in different scenarios. Currently we are using common code WLAN_REASON_DEAUTH_LEAVING for these cases. This patch adds support to parse an actual reason code from firmware event body and send it to cfg80211. WLAN_REASON_DEAUTH_LEAVING code is used if deauth is initiated by our device. Signed-off-by: Amitkumar Karwar <akarwar@marvell.com> Signed-off-by: Bing Zhao <bzhao@marvell.com> Signed-off-by: John W.

2012-09-28mwifiex: send firmware initialization commands synchronouslyStone Piao
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.

2012-09-11mwifiex: update adapter->bss_prio_tbl[j].bss_prio_cur correctlyAmitkumar Karwar
"adapter->bss_prio_tbl[j].bss_prio_head" points to linked list of interfaces with priority 'j'. "bss_prio_tbl[j].bss_prio_cur" is supposed to point to next interface every time the routine for dequeuing the packet is called. This ensures that each interface gets fair chance. Currently we have AP and station interfaces with priority '0'. Therefore "adapter->bss_prio_tbl[0].bss_prio_cur" should alternately point to AP and station nodes. Since "bss_prio_cur" is not correctly updated, for each packet picked for AP, two packets are picked for station interface. This patch fixes the problem by correctly updating "bss_prio_cur".

2012-09-11mwifiex: have same priority for AP and station trafficAmitkumar Karwar
Currently AP interface has higher priority over station. Hence separate entries are created in "adapter->bss_prio_tbl" for these interfaces and station packet is dequeued only if there is not packet in queue for AP. It is observed that ping for station interface doesn't work if heavy traffic is running on AP. The problem is fixed by having same priority for both the interfaces. This patch also removes an extra initialisation for "priv->bss_priority". Signed-off-by: Amitkumar Karwar <akarwar@marvell.com> Signed-off-by: Bing Zhao <bzhao@marvell.com> Signed-off-by: John W.
