The baseband and cycle counters are being sampled during ani processing for debugging purpose. Whenever the ani is postponded due to sleep state, taking samples on that time is of no use and also unneccesarily waking up the chip might increase the power consumption on idle associated state. Hence moving debug function within powersave block. Signed-off-by:

When WLAN enter full sleep mode, WLAN HW should send out a LNA_TAKE message for BT to take control of the shared LNA. Otherwise BT traffic is completely stopped whenever the wlan interface is moved full sleep mode. Signed-off-by:

During driver stop, btcoex is disabled and also btcoex_hw.enabled is set to false. Afterwards mci_is_enabled returns false so that BT is not gaining SPDT control on WLAN sleep. Fix that. Signed-off-by:

WLAN driver initialization is muting BT which is terminating the ongoing BT traffic. The reason to mute BT is to avoid any incoming MCI messages from BT when MCI reset is in progress that could corrupt WLAN MCI RX state machine. But we should not dedicate radio completely to WLAN in driver init itself. So this patch removes the wlan weightage changes from mute BT to retain BT connection. Signed-off-by:

Two MCI interrupts are generated while adding A2DP and headset profiles with different types and same connection handle. While disconnecting, only one MCI interrupt is generated with last added profile type value for both profiles. While adding second profile type decrement first one. Signed-off-by:

Firmware supports changing filters using ACX_RX_CFG command, so use it in .configure_filter callback. Firmware also supports probe request filtering, so add it too along the way. This will also re-enable BSSID filter which is now removed by join command while associating. Signed-off-by:

This driver has a hack in cmd.c which effectively disables all filtering. This seems to be triggering a firmware bug where it stops reporting any rx packets after random time on some routers, which is eliminated (or at least appears much more rarely) when filtering is on. I have found that only BSSID filter needs to be disabled for association to work, so disable only that instead of all filtering. Signed-off-by:

The brcmsmac internal regulatory data is being used to determine whether OFDM should be allowed, and this is only done once during initialization. To be effective this needs to be checked against mac80211's regulatory rules for the current channel. Reviewed-by:

The core regulatory support will disable channels not allowed by regulatory rules, so brcmsmac doesn't need to check whether or not the requested channel is permitted by regulatory. Reviewed-by:

Currently the limits from the internal X2 domain are used, regardless of what regulatory rules are in effect. Instead use the power limits set by the higher-level regulatory support. The rules for the MIMO power limits are still always derived from the world domain, pending guidance from Broadcom as to how these need to be handled. This will be fixed later, but using the limits from the world domain works for now. Reviewed-by:

Currently the radio disable state is only updated during initialization, and it's only checked against the internal world domain. This is unnecessary, as there are always valid channels against this domain. Instead, check whether any channels are enabled in the regulatory notifier and update the radio state accordingly.

brcmsmac implements enforcement of regulatory constraints internally, using a Broadcom-specific world roaming domain named X2. Besides being duplication of functionality this can also conflict with mac80211's regulatory implementation, as mac80211 is unaware of the X2 domain and thus might apply a more restrictive domain. This patch is the first step in making brcmsmac cooperate with mac80211's regulatory support. X2 is registered as a custom domain with mac80211, so that at least both implementations will be enforcing the same set of constraints. The internal enforcement of rules is kept for now; this will be converted over to relying on mac80211 regulatory enforcement in later patches. Reviewed-by:

This code has been kept around in anticipation of adding support for 40MHz channels, but subsequent patches to better integrate with mac80211 regulatory support will render it completely broken. Therefore we should go ahead and remove it. Keep these changes separate from other cleanup patches in order to make it easier to resurrect 40MHz channel support at some point in the future.

In some situations brcmsmac is choosing a channel internally. This makes it difficult at times to know what channel to use for enforcing regulatory constraints, so instead always use the channel from the mac80211 configuration. Reviewed-by:

This code is unnecessary, and in fact it's never executed because the interface is never up when brcms_c_channels_commit() is called. Removing it helps simplify the implementation of proper regulatory support. Reviewed-by:

This patch adds functionality to set channel info received from cfg80211_ap_settings in start_ap handler. Since set_channel cfg80211 handler has been removed and we need not explicitely call mwifiex_uap_set_channel(); hence this function definition is also removed. Signed-off-by:

Commit "ath9k_hw: improve ANI processing and rx desensitizing parameters" was unifying some code related to overriding OFDM weak signal detection, but seems to have gotten some of the original intent wrong, probably because of a misnamed variable. The beacon RSSI is only valid in station mode, and the main reason to check it in ath9k_hw_set_ofdm_nil is to make sure that OFDM weak signal detection stays enabled if the RSSI is low, even when the OFDM noise immunity entry is supposed to disable it. The above commit removed the mode checks and changed the code so that OFDM weak signal detection would only be changed if the rssi is high, which is wrong for everything but client mode. This patch restores the old behavior in a simplified form. Signed-off-by:

The effect of using a short single-channel scan to reset the radio is that scanning a channel that isn't in use needs to re-tune the radio. This means that the dwell time is irrelevant, so use a shorter time. While at it, clean up the code for this a bit. Reviewed-by:
