2025-11-18wifi: rtw89: phy: ignore DCFO if not defined in chip_infoPing-Ke Shih
For WiFi 7 chips, DCFO (digital carrier frequency offset) feature isn't supported, so the corresponding registers aren't defined in chip_info. Check and ignore this feature accordingly.

2025-11-18wifi: rtw89: phy: calling BB pre-init by chips with/without BB MCUPing-Ke Shih
The existing flow is doing BB pre-init before downloading BB MCU firmware, because existing chip RTL8922A has BB MCU. However, the coming chips don't have this, and BB pre-init configuring registers can affect downloading WiFi-CPU firmware. Therefore, calling BB pre-init afterward for new coming chips without BB MCU. For existing WiFi 6 chips, no BB pre-init. For RTL8922A, don't change the logic.

2025-11-18wifi: rtw89: flush TX queue before deleting keyChih-Kang Chang
In the wpa_supplicant rekey flow, it sends an EAPOL packet 4/4 through nl80211_tx_control_port() and triggers wake_tx_queue() in the driver. Then, it sends nl80211_new_key() to configure a new key in mac80211. However, in wake_tx_queue(), a workqueue is used to process the TX packet, which might cause the driver to process the EAPOL packet later than nl80211_new_key(). This results in the EAPOL packet 4/4 being transmitted with the new key and IV, causing it to be dropped by the AP. Therefore, needs to flush TX queue before deleting the old key to ensure that the EAPOL 4/4 packet is transmitted using the old key.

2025-11-12wifi: iwlwifi: mld: always take beacon ies in link gradingMiri Korenblit
One of the factors of a link's grade is the channel load, which is calculated from the AP's bss load element. The current code takes this element from the beacon for an active link, and from bss->ies for an inactive link. bss->ies is set to either the beacon's ies or to the probe response ones, with preference to the probe response (meaning that if there was even one probe response, the ies of it will be stored in bss->ies and won't be overiden by the beacon ies). The probe response can be very old, i.e. from the connection time, where a beacon is updated before each link selection (which is triggered only after a passive scan). In such case, the bss load element in the probe response will not include the channel load caused by the STA, where the beacon will. This will cause the inactive link to always have a lower channel load, and therefore an higher grade than the active link's one. This causes repeated link switches, causing the throughput to drop. Fix this by always taking the ies from the beacon, as those are for sure new.

2025-11-11wifi: mwl8k: inject DSSS Parameter Set element into beacons if missingPawel Dembicki
Some Marvell AP firmware used with mwl8k misbehaves when beacon frames do not contain a WLAN_EID_DS_PARAMS element with the current channel. It was reported on OpenWrt Github issues [0]. When hostapd/mac80211 omits DSSS Parameter Set from the beacon (which is valid on some bands), the firmware stops transmitting sane frames and RX status starts reporting bogus channel information. This makes AP mode unusable. Newer Marvell drivers (mwlwifi [1]) hard-code DSSS Parameter Set into AP beacons for all chips, which suggests this is a firmware requirement rather than a mwl8k-specific quirk. Mirror that behaviour in mwl8k: when setting the beacon, check if WLAN_EID_DS_PARAMS is present, and if not, extend the beacon and inject a DSSS Parameter Set element, using the current channel from hw->conf.chandef.chan. Tested on Linksys EA4500 (88W8366).

2025-11-06wifi: ath12k: Fix timeout error during beacon stats retrievalManish Dharanenthiran
Currently, for beacon_stats, ath12k_mac_get_fw_stats() is called for each started BSS on the specified hardware. ath12k_mac_get_fw_stats() will wait for the fw_stats_done completion after fetching the requested data from firmware. For the beacon_stats, fw_stats_done completion will be set only when stats are received for all BSSes. However, for other stats like vdev_stats or pdev_stats, there is one request to the firmware for all enabled BSSes. Since beacon_stats is fetched individually for all BSSes enabled in that pdev, waiting for the completion event results in a timeout error when multiple BSSes are enabled. Avoid this by completing the fw_stats_done immediately after updating the requested BSS's beacon stats in the list. Subsequently, this list will be used to display the beacon stats for all enabled BSSes in the requested pdev. Additionally, remove 'num_bcn_recvd' from the ath12k_fw_stats struct as it is no longer needed.

2025-11-06wifi: ath12k: Make firmware stats reset caller-drivenManish Dharanenthiran
Currently, ath12k_fw_stats_reset() is called in ath12k_mac_get_fw_stats() before fetching the required stats from the firmware. However, ath12k_open_bcn_stats() requests firmware stats for each enabled BSS individually. Since the firmware stats are reset before fetching, only the last BSS's data is displayed. Also, in ath12k_mac_op_get_txpower(), ath12k_mac_op_sta_statistics(), and ath12k_mac_op_link_sta_statistics(), after getting the stats from the firmware, the reset function is not called until the next firmware stats are requested or while unloading the module. Hence, the stats buffer will not be freed until one of the above sequences is executed. However, in ath12k_open_vdev_stats(), ath12k_open_bcn_stats() and ath12k_open_pdev_stats(), firmware stats are reset after copying the necessary data in ath12k_wmi_fw_stats_dump(). This leads to inconsistent usage of ath12k_fw_stats_reset() for freeing the firmware stats. Avoid these discrepancies by making it the caller's responsibility to free the stats buffer, thereby removing the need to free the stats buffer in ath12k_mac_get_fw_stats() and ath12k_wmi_fw_stats_dump().

2025-11-06wifi: ath11k: zero init info->status in wmi_process_mgmt_tx_comp()Nicolas Escande
When reporting tx completion using ieee80211_tx_status_xxx() family of functions, the status part of the struct ieee80211_tx_info nested in the skb is used to report things like transmit rates & retry count to mac80211 On the TX data path, this is correctly memset to 0 before calling ieee80211_tx_status_ext(), but on the tx mgmt path this was not done. This leads to mac80211 treating garbage values as valid transmit counters (like tx retries for example) and accounting them as real statistics that makes their way to userland via station dump.

2025-11-06wifi: rtw89: process TX wait skbs for USB via C2H handlerFedor Pchelkin
TX wait skbs need to be completed when they are done. PCIe part does this inside rtw89_pci_tx_status() during RPP processing. Other HCIs use a mechanism based on C2H firmware messages. Store TX wait skbs inside TX report queue so that it'll be possible to identify completed items inside the C2H handler. Try to do this as similar to PCIe path as possible. When the corresponding TX wait skb is found inside TX report queue, unlink it from there and call rtw89_core_tx_wait_complete() to mark the completion. If the callee waiting for the completion has already timed out, the TX wait skb is placed into TX wait list (like PCIe part does). It's important that during HCI reset all pending TX wait frames should be completed inside hci.ops->reset method before calling rtw89_tx_wait_list_clear().
