2025-10-28wifi: iwlwifi: tests: check listed PCI IDs have configsJohannes Berg
Add a test that checks, for the old pre-CNVI devices, that PCI IDs listed in the PCI IDs table will also match in the config table. Newer ones we test against our database of devices, but the current database doesn't go back that far, so at least this checks against the PCI IDs the driver has.

2025-10-28wifi: iwlwifi: mld: reschedule check_tpt_wk also not in EMLSRMiri Korenblit
When the throughput count reaches the threshold, EMLSR is no longer blocked by throughput. This doesn't mean that EMLSR will be activated immediately, since there might be other reasons that block EMLSR. When the throughput blocker is not set, check_tpt_wk should run every 5 seconds and check if the throughput blocker should be set (if the throughtput counter dropped). If not, it should reschedule itself. In the current code, the worker will reschedule itself only if we are in EMLSR. This is wrong, since we might be in a case where the throughput blocker is not set but we are not in EMLSR, and then we will never check again the throughput counters (and block EMLSR if needed). Fix this by rescheduling the worker also when EMLSR is not active.

2025-10-28net/mlx5: Add balance ID support for LAG multiplane groupsMark Bloch
Implement balance ID support for multiplane LAG configurations. This feature enables per-multiplane group load balancing by extending the software system image GUID with a balance ID component. Key implementations: - Enable lag_per_mp_group capability when supported by hardware. - Append load_balance_id to software system image GUID when conditions are met. - Increase MLX5_SW_IMAGE_GUID_MAX_BYTES from 8 to 9 to accommodate the extra byte. The balance ID is appended to the system image GUID only when both load_balance_id and lag_per_mp_group capabilities are available, ensuring backward compatibility while enabling enhanced LAG functionality. This enhancement allows for more granular load balancing control in complex multi-plane LAG deployments, improving network performance and flexibility.

2025-10-27wifi: ath12k: Use ath12k_dp_peer in per packet Tx & Rx pathsHarsh Kumar Bijlani
Move link agnostic data path parameters (keys, rx_tid, reorder buffers, MIC context etc) from ath12k_sta and ath12k_dp_link_peer into ath12k_dp_peer. These parameters are shared across MLO links and should be managed at the peer level. Configure them only when the link peer is primary to avoid redundancy and ensure consistent setup. Switch per-packet Tx/Rx paths and monitor paths to look up ath12k_dp_peer and ath12k_dp_link_peer via peer_id. Helper APIs added: - ath12k_dp_peer_find_by_peerid() - ath12k_dp_link_peer_find_by_peerid() Ensure RCU read lock is held when using these helpers APIs. With the above API ath12k_dp_link_peer_find_by_peerid() being used to find ath12k_dp_link_peer, existing API ath12k_dp_link_peer_find_by_id() is required only at the time of unmap event from firmware since it fetches the ath12k_dp_link_peer from linked list. In order to restrict the usage of API ath12k_dp_link_peer_find_by_id(), make it static and also rename it to ath12k_dp_link_peer_search_by_id().

2025-10-27wifi: ath12k: Attach and detach ath12k_dp_link_peer to ath12k_dp_peerHarsh Kumar Bijlani
Introduce explicit attach/detach of ath12k_dp_link_peer objects to their parent ath12k_dp_peer to formalize the data path station hierarchy: ath12k_dp_peer | |--> ath12k_dp_link_peer | |--> ath12k_dp_link_peer | |--> ath12k_dp_link_peer ath12k_dp_peer maintains an array of RCU-protected pointers "link_peers[ATH12K_NUM_MAX_LINKS]" to ath12k_dp_link_peer indexed by its protocol_link_id, and each ath12k_dp_link_peer holds a back pointer to its parent ath12k_dp_peer. Attach is performed after link peer creation, and detach occurs before link peer deletion. This ensures consistent lifetime management and safe concurrent access. ath12k_dp_peer also maintains an array "hw_links[ATH12K_GROUP_MAX_RADIO]" to store the mapping between hw_link_id and protocol_link_id for each of the ath12k_dp_link_peer. RCU locking/unlocking rules: - Readers must hold rcu_read_lock() and fetch the pointer with rcu_dereference(dp_peer->link[link_id]); drop with rcu_read_unlock() when done. - Writers publish with rcu_assign_pointer() and reclaim only after synchronize_rcu(). Handle the case of detachment of link peer from ath12k_dp_peer in case of core reset.

2025-10-27wifi: ath12k: Define ath12k_dp_peer structure & APIs for create & deleteHarsh Kumar Bijlani
Define the structure of ath12k_dp_peer and also define APIs for creation and deletion of ath12k_dp_peer based on STA state, as the ath12k_dp_peer is intended to be used in the subsequent set of patches. Maintain ath12k_dp_peer in a linked list in ath12k_dp_hw (which is a datapath component of ath12k_hw) and protect this list using spinlock "peer_lock". Store peer id based table (array of RCU pointers) of ath12k_dp_peer in ath12k_dp_hw. Use this peer id table to refer in the per packet Tx and Rx paths as it provides faster access to ath12k_dp_peer in comparison to linked list iterative search using peer id or mac address. Add support to handle deletion of ath12k_dp_peer in case of core reset. This patch is adding and deleting ath12k_dp_peer created for MLO STA to the above mentioned RCU pointer table. Addition and deletion of ath12k_dp_peer for non-MLO STA to RCU pointer table is handled in the subsequent following patch. Structure ath12k_ml_peer is created and deleted for MLO peers at the time of connect and disconnect and there is no other use case of it. With the above design in place for ath12k_dp_peer, ath12k_ml_peer becomes redundant.

2025-10-27wifi: ath12k: Add hash table for ath12k_dp_link_peerHarsh Kumar Bijlani
There is a linked list of ath12k_dp_link_peer maintained in ath12k_dp. For link peer search based on mac address, there is iteration over the list wherein the mac address are compared for each entry in the list. This search operation is a costly operation considering the time complexity involved. In order to reduce the complexity, add hash table for ath12k_dp_link_peer in ath12k_dp where mac address of the link peer is used to derive the hash index. This hash table is lock protected by spinlock "dp_lock" present in ath12k_dp. This hash table is currently used for search of link peer using mac address for any interaction between control path and data path, per packet Rx monitor path and regular multicast Tx path. Update API ath12k_dp_link_peer_find_by_addr() to make use of the hash table for search operation using mac address, while other search APIs still rely on linked list. ath11k driver has been taken as reference for implementation of hash table.

2025-10-27wifi: ath12k: Add hash table for ath12k_link_sta in ath12k_baseHarsh Kumar Bijlani
Currently ath12k_base maintains a linked list of ath12k_dp_link_peer as "peers". This linked list is used for all kinds of peer search operations. In the control path, if there is a requirement to search for ath12k_link_sta using mac address, then below sequence is to be followed: 1. Find ath12k_dp_link_peer in the linked list using mac address 2. Fetch ieee80211_sta from ath12k_dp_link_peer 3. Fetch ath12k_sta from ieee80211_sta 4. Finally fetch ath12k_link_sta from ath12k_sta using link_id In the above sequence, there are too many indirections involved. In order to simplify this, add hash table for ath12k_link_sta in ath12k_base. This hash table is lock protected by existing spinlock "base_lock" in ath12k_base as this table can be concurrently accessed in different contexts. Use this table for ath12k_link_sta search operations using mac address in the control path. Ex: For WMI interface and mac80211_ops interface in the control path, sta mac address is received and this hash table can be used to search for ath12k_link_sta directly instead of following the longer route mentioned above. Helper APIs added: - ath12k_link_sta_rhash_add() - To add arsta entry to hash table - ath12k_link_sta_rhash_delete() - To remove arsta entry from hash table - ath12k_link_sta_find_by_addr() - To find arsta from hash table using mac address Make changes in API ath12k_peer_sta_kickout_event() to find arsta using above mechanism. ath11k driver has been taken as reference for implementation of hash table.

For each ath12k_link_sta, there is a corresponding data path peer which is represented by struct ath12k_peer. Diagrammatic view of the station is as below: ath12k_sta | |-> ath12k_link_sta <--> ath12k_peer | |-> ath12k_link_sta <--> ath12k_peer | |-> ath12k_link_sta <--> ath12k_peer Currently, in control path, ath12k_link_sta and ath12k_peer are used interchangeably, while the data path makes use of ath12k_peer only. For ath12k next-generation driver framework, in order to have a clean segregation between control and data path, use ath12k_link_sta only for control path operations. Station view for the data path is revamped as below: ath12k_dp_peer | |-> ath12k_dp_link_peer | |-> ath12k_dp_link_peer | |-> ath12k_dp_link_peer Introduce the structure ath12k_dp_peer to represent the data path version of corresponding ath12k_sta. This ath12k_dp_peer contains the fields used in the per packet Tx Rx paths applicable across all the links and maintains an array of ath12k_dp_link_peer. Per packet Tx and Rx path operates on ath12k_dp_peer. This ath12k_dp_peer is a standalone new object and has back pointer reference to ieee80211_sta. Rename ath12k_peer to ath12k_dp_link_peer and move the fields which are common across all the links to ath12k_dp_peer. Add the fields specific to a link which are mostly for statistics and monitor usage to ath12k_dp_link_peer.

2025-10-27wifi: mac80211_hwsim: advertise puncturing feature supportAditya Kumar Singh
If userspace provides a puncturing bitmap via the NL80211_ATTR_PUNCT_BITMAP attribute, the kernel with mac80211_hwsim driver currently rejects the command with the error: "driver doesn't support puncturing", because the driver does not advertise support for this feature. At present, the following hwsim test cases utilize puncturing, but the bitmap is not sent to the kernel. Instead, the puncturing information is conveyed only through the beacon data: * eht_5ghz_80mhz_puncturing_override_1 * eht_5ghz_80mhz_puncturing_override_2 * eht_5ghz_80mhz_puncturing_override_3 A future change in hostapd will begin configuring the puncturing bitmap explicitly, which will cause these test cases to fail unless the driver advertises support.

While the DP83867 PHYs report EEE capability through their feature registers, the actual hardware does not support EEE (see Links). When the connected MAC enables EEE, it causes link instability and communication failures. The issue is reproducible with a iMX8MP and relevant stmmac ethernet port. Since the introduction of phylink-managed EEE support in the stmmac driver, EEE is now enabled by default, leading to issues on systems using the DP83867 PHY. Call phy_disable_eee during phy initialization to prevent EEE from being enabled on DP83867 PHYs.
