The functions for communicating were given the net_device only because its private data contained struct brcmf_if object. However, not all firmware related interfaces will be associated with a net_device. To accomodate provisioning firmware for such interfaces the struct brcmf_if object will be passed to the fwil functions. Reviewed-by:

The firmware carries channel information in a different format as the provided ieee80211_channel structure. Conversion is needed when receiving requests from cfg80211 carrying ieee80211_channel structures. This patch adds a utility function to do that. Reviewed-by:

The firmware interface has functions to send bsscfg specific commands to the device. These functions currently have a bssidx parameter, but that same information is stored in struct brcmf_if, which is in the private data of the net_device parameter. Reviewed-by:

In brcmf_bus_start() a number of settings are sent to the device. For this functions are used that bypass the common firmware interface. By reordering the code in brcmf_bus_start() this bypass can be removed. Signed-off-by:

When the firmware notifies the driver about adding a new interface it also provides an index for the bss associated with this interface. This index will be needed for upcoming features like peer-to-peer. By adding this index in struct brcmf_if it is easy to obtain as this will be associated with the net_device private data.

carl9170_handle_mpdu is the final part of the rx path of the driver. It splits the raw data streams from the device into skb packets and passes them on to mac80211. As a result of continuous updates, it grew over the years when new code was added by the following commits: - report A-MPDU status - fix HT peer BA session corruption - A-MPDU frame type filter - ... This patch splits the routine into two stages. The first stage only deals with the details about extracting and verifying the data from the incoming stream. Whereas the second stage packs it into skbs and passes it on to mac80211. Reported-by:

We derive mwifiex_private structure which is per interface from received skb's rx_info. Once priv is derived, same priv can be propagated to other functions instead of callee deriving priv from rx_info again. Signed-off-by:

This reverts commit 34202e28 We made "34202ee.." because we didn't support custom regulatory rules at that time. But now we use our own custom regulatory rules, so it needs to be changed back. Also, chan->max_power calculations in cfg80211 were broken. Hence we started using chan->max_reg_power. Now it has got fixed in following commit. commit 5e31fc08 Author: Stanislaw Gruszka <sgruszka@redhat.com> Date: Tue Jul 24 08:35:39 2012 +0200 wireless: reg: restore previous behaviour of chan->max_power calculations Hence we will use chan->max_power instead of chan->max_reg_power.

If MWIFIEX_DISABLE_CHAN_FILT bit in scan mode bitmap is set, firmware will turn off the filtering of scan responses from adjacent channels. Currently the bit is set only for internal SSID specific scan performed during association. We will set it for user requested SSID specific scan as well. Signed-off-by:

mwifiex_request_scan() takes care of synchronous internal scan performed by driver during association. Currently the semaphore acquired for the scan is unnecessarily released at the end of different paths. Also, failure paths returning error code other than "-1" are not considered. We will release it at the end of routine to fix above issues. Signed-off-by:

When the interface is down, we will abort scan by calling cfg80211_scan_done() with abort option. This fixes WARN_ON triggered by cfg80211 in wdev_cleanup_work(). Driver's internal variables/flags are cleared once we get response for current scan command. Meanwhile we will block new scan request from cfg80211. Signed-off-by:

This will fix warnings like following when CONFIG_PM_SLEEP is not set: warning: 'xxx_suspend' defined but not used [-Wunused-function] warning: 'xxx_resume' defined but not used [-Wunused-function] Because SET_SYSTEM_SLEEP_PM_OPS(suspend_fn, resume_fn) Only references the callbacks on CONFIG_PM_SLEEP (instead of CONFIG_PM).

When the BT connection is initiated by headset, it's possible that headset requests to make one A2DP and one Voice connection over the same link. BT firmware will send a new profile A2DP_Voice in this case. So WLAN has to take care of this new profile for tuning BTCOEX parameters. Signed-off-by:

While resuming from S3, BT host issues HCI reset command and it causes BT firmware to busy with security key calculation. At this movement, WLAN detects MCI hardware error of MCI_CONT_INFO_TIMEOUT and then it starts the recovery sequence repeatedly. Too many recovery sequences would exhaust the BT kernel message pool. This patch imposes a duration between consecutive BT recovery procedure. Thus it solves BT firmware panic issue reported in AR9565. Signed-off-by:

Self generated MCI messages is configured to use chain 1. As ar9565 is 1x1 solution, It can not use Chain 1. Hence fix Chain 1 for ar9462 alone. Not doing so, could affect WLAN connectivity in ar9565 as LNA sharing is not informed by BT. Signed-off-by:

The simulataneous transmission of both WLAN and BT might cause increase in power levels. To avoid regulatory violation, WLAN tx power will be adjusted according to BT power index based on avaliability of BT scheduling messages. WLAN tx power reduction might affect its performance. So WLAN tx power is only be lowered when the signal strength is good enough. Otherwise concurrent tx will be disabled and WLAN uses it default power levels. Also concurrent tx is disabled whenever WLAN is moving to off-channel which might be used by BT. Signed-off-by:

This feature enables both WLAN and BT can transmit simultaneously by setting WLAN and BT to equal priorities. Whenever both are transmitting, it might violate regulatory power limits. To avoid regulatory violation, WLAN tx power will be adjusted according to BT power index based on avaliability of BT scheduling message. If the combined power exceeds threshold, BT transmission will be held off. Signed-off-by:

WLAN updates channel bitmap when associated and disassociated. Channel bitmap will reflect whare are the channels used or affected by WLAN and BT should avoid using those. Not doing so, could affect BT traffic as both WLAN and BT is operating on same channel. Signed-off-by:

When WLAN is idle ensure we downgrade to FTP_STOMP_LOW weight (from STOMP_LOW) to provide more bandwidth for BT FTP profile. WLAN's idleness can be estimated by taking into account of the rx data packets and just ignore beacons, qos nullfunc etc. Also update bt_wait_time even if the chip is in NETWORK SLEEP mode. This should help BT throughput when WLAN is idle. Signed-off-by:
