2025-06-25wifi: iwlwifi: defer MLO scan after link activationJohannes Berg
Doing a scan right after link activation can be less reliable than at other times, as the firmware is still busy trying to catch beacons from the just activated link, etc. In case a new MLO scan request comes in, defer it for a few seconds after a link activation.

2025-05-10wifi: iwlwifi: mld: Block EMLSR only when ready to enter ROCPagadala Yesu Anjaneyulu
If one of the stages in starting a ROC failed, the ROC will not start nor end so EMLSR will stay blocked forever. Block EMLSR once all ROC conditions are validated and clear EMLSR blocked reasons in mld_vif cleanup.

2025-05-10wifi: iwlwifi: mld: move aux_sta member from iwl_mld_link to iwl_mld_vifPagadala Yesu Anjaneyulu
This change reflects the correct ownership of aux_sta, as it is not a property of the link but rather of the virtual interface. Updated the initialization, cleanup and access logic for the aux_sta member to align with its new location within iwl_mld_vif.

2025-05-10wifi: iwlwifi: mld: Fix ROC activity cleanup in iwl_mld_vifPagadala Yesu Anjaneyulu
The roc_activity member in the iwl_mld_vif structure was previously set to zero during cleanup as was present in struct_group, which incorrectly indicated ROC_ACTIVITY_HOTSPOT. To fix this issue, remove roc_activity member from struct_group. Notify mac80211 of ROC expiration during vif cleanup to maintain synchronization between the driver and mac80211. While on it, update it's type to enum iwl_roc_activity.

2025-04-23wifi: iwlwifi: mld: remove P2P powersave trackingJohannes Berg
Since the FW is tracking the CT window by itself, we don't need to update the MAC context or even fill in the value. We just had added that because a firmware bug had broken it for a while.

2025-03-11wifi: iwlwifi: mld: assume wiphy is locked when getting BSS ifacesBenjamin Berg
The code was calling ieee80211_iterate_interfaces, however that takes a lock of iflist_mtx, which must not be taken recursively. Fix this by using the appropriate _mtx version that asserts that the wiphy mutex is already held.

2025-03-05wifi: iwlwifi: add iwlmld sub-driverMiri Korenblit
iwlwifi is the driver of all Intel wifi devices since 2008. Since then, the hardware has changed a lot, but the firmware API has changed even more. The need to keep one driver that supports all those different APIs led us to introduce a new architecture circa 2012 which allowed us to keep the same interface to the hardware (DMAs, Tx queues, etc...) with a new layer to implement the mid-layer between mac80211 and the firmware. The first component is called the 'transport' and the latter is called 'operation_mode' a.k.a op_mode. In 2013 we took advantage of the new architecture to introduce iwlmvm which allowed us to implement the, then, new firmware API. This op_mode supports 7260 and up, those devices supports support at least VHT. Since then, wifi evolved and so did the firmware. It became much bigger and took a lot of functionality from the driver. It became increasingly hard to keep the same op_mode for the newest devices and we experienced frequent regressions on older devices. In order to avoid those regressions and keep the code maintainable, we decided it was about time to start a new op_mode. iwlmld is a new op_mode that supports BE200 or newer if the firmware being used is 97.ucode or newer. If the user has an older devices or BE200 with .96.ucode, iwlmvm will be loaded. Of course, this op_mode selection is seamless. All the features supported in iwlmvm are supported in iwlmld besides a few seldom used use cases: injection and Hotspot 2.0. Those are under work. A few points about the implementation: * iwlmld doesn't have any mutexes, it relies on the wiphy_lock * iwlmld is more "resource oriented": stations, links and interfaces are allocated and freed only after all the relevant flows are completed. * Firmware notifications' sizes are validated in a more structured way. We would love to see this new op_mode merged in 6.15. The firmware for this new driver (.97.ucode) is not yet publicly available but it'll be sent very soon. People eager to get an early version of this firmware can contact Emmanuel at: emmanuel.grumbach@intel.com I've listed the people who directly contributed code, but many others from various teams have contributed in other ways.
