This patch disables HW peak detect calibration for QCA953x, since it is problematic on a few boards. Instead, manual calibration will be done in the driver. Signed-off-by:

b43 has a FIXME about locking in the mac80211 set-beacon-int callback for a long time. As it turns out there actually is a tiny race window that could result in a use-after-free bug of the 'current_beacon' memory. Nobody ever reported this, so it probably never happened. Fix this by adding a spin lock that protects the current_beacon access. We must not be in atomic context while accessing hardware (due to SDIO), so the beacon update bottom half has to clone the skb and release the lock before writing it to hardware. Let's all hope that this stops the troll who is trying to submit incorrect fixes for this issue repeatedly. And let's hope that I'm not a troll, too, who just hides even more evil code in an even more complex attempt to fix the issue. Signed-off-by:

This patch enables 11h extensions in FW upon detecting DFS channel in start radar detection/channel switch handlers. Patch also takes care of disabling 11h when non DFS channels are to be set during start_ap handler. Signed-off-by:

This patch adds cfg80211 channel_switch support for mwifiex. Upon receiving channel switch request, driver would parse channel switch announcement IE from beacon_data. If TX is blocked, netdev queues are stopped. IEs from csa_beacon are then parsed and set to FW. Signed-off-by:

This patch adds support for radar_detected event from FW. Driver in turn would stop netdev queues to stop TX traffic and issue RADAR_DETECT event to cfg80211. Signed-off-by:

This patch adds support for channel report enabling. Channel report event happens if radar is detected on specified channel after driver has issued radar detect command within CAC time. Driver in turn sends RADAR_DETECTED event to cfg80211 to tell radar was detected within CAC time. Signed-off-by:

This patch adds support for cfg80211 start_radar_detection handler. Upon reception of start_radar_detection, driver prepares radar detect command to FW. Delayed work is queued for CAC time which sends radar detection finished event to cfg80211. Signed-off-by:

Currently interface limits are checked by seeing if bss_mode for particular priv is set. If bss_mode is not set, interface creation is allowed. This patch adds framework to initializes maximum virtual interfaces supported during load time and check current number of interfaces created agains allowed interface limit during new virtual interface creation.

wdev is used even after del_virtual_interface handler in cfg80211 in nl80211_post_doit. Since we have freed wdev in handling of del_virtual_intf, this can result into crash while deleting interface. Avoid this be not declaring wdev which part of mwifiex_private structure but struct wireless_dev type. Signed-off-by:

The nvram file can hold a key=value combination in which the value may have spaces, ie. 'RAW1=80 02 fe ff'. The parsing functionality did not deal with this so it gives an error message: [621746.311635] brcmfmac: brcmf_nvram_handle_key warning: ln=90:col=11: '=' expected, skip invalid key entry because RAW1=80 is being considerd as key=value pair and it expects '=' sign after '02' for next key=value pair. This entry can be completely ignored as firmware does not need it. Reviewed-by:

During suspend the bus state is put in the down state. When data is being transmitted during this state then the netdev queue will be close. This patch will wake the queue on state data if the queue was closed. Reviewed-by:

Each bus driver is maintaing an exported bus state indicating if upper layers can or cannot send data. SDIO is using this state also for more private states. This makes handling the states and state changes complex. This patch minimises the exposed states and makes SDIO keep track of an internal state where necessary. Reviewed-by:

Before going in suspend state the watchdog thread needs to put the device in bus sleep state, which assures it can go in deep-sleep state during D3 state. Reviewed-by:

The driver always called cfg80211_disconnected() with reason parameter set to zero, ie. unknown. However, firmware does provide a valid 802.11 reason code in DEAUTH and DISASSOC event message to the driver. This patch passes the reason code to cfg80211_disconnected(). Reviewed-by:
