2025-08-19wifi: rtw89: fix group frames loss when connected to non-transmitted BSSIDKuan-Chung Chen
When STA connects to AP with dot11MultiBSSIDImplemented set to true, the layout of the TIM element's Partial Virtual Bitmap changes. Bits 1 to (2^n - 1) are used to indicate buffered group addressed frames (e.g., broadcast/multicast) for non-transmitted BSSIDs.

2025-08-19wifi: rtw89: introduce beacon tracking to improve connection stabilityKuan-Chung Chen
In ideal scenario, AP's beacon should transmit at the Target Beacon Transmission Time (TBTT). However, in practice, beacon may be slightly off-schedule. This beacon "drift" prevents the firmware from receiving beacon at the expected TBTT, leading to connection disruptions. To address this, we introduce beacon tracking mechanism to enhance overall connection stability. This mechanism executes the following steps in each cycle (2 seconds): 1) Based on the last 32 received beacons, compute the minimum TBTT offset to use for the next cycle 2) Using the same 32 beacons, calculate the drift of each. A histogram is plotted, and outliers are identified using a boxplot. 3) According to the statistical results from the second step, a maximum receive window size (beacon timeout) is selected to cover approximately 80% of the beacons and applied to the next cycle.

The register REG_SYS_CFG1 is used to determine chip basic information as arguments of following flows, such as download firmware and load PHY parameters, so driver read the value early (before power-on).

2025-07-23wifi: brcmfmac: fix EXTSAE WPA3 connection failure due to AUTH TX failureTing-Ying Li
For WPA3-SAE Connection in EXTSAE mode, the userspace daemon is allowed to generate the SAE Auth frames. The driver uses the "mgmt_frame" FW IOVAR to transmit this MGMT frame. Before sending the IOVAR, the Driver is incorrectly treating the channel number read from the FW as a frequency value and again attempts to convert this into a channel number using ieee80211_frequency_to_channel(). This added an invalid channel number as part of the IOVAR request to the FW And some FW which strictly expects a valid channel would return BAD_CHAN error, while failing to transmit the driver requested SAE Auth MGMT frame. Fix this in the CYW vendor specific MGMT TX cfg80211 ops handler, by not treating the channel number read from the FW as frequency value and skip the attempt to convert it again into a channel number. Also fix this in the generic MGMT TX cfg80211 ops handler.

2025-07-23wifi: iwlwifi: stop supporting iwl_omi_send_status_notif ver 1Miri Korenblit
This version doesn't provide the sta id, so we need to look it up - assuming that no other sta exists, since one of the conditions of entering OMI is not having P2P/TDLS. But when we leave OMI, because of the P2P/TDLS activation, the P2P/TDLS sta can already exist while we receive the notification from the FW. This causes an error log which is incorrect. Since OMI is only supported in SC, which is not shipped yet, no one will use a FW with the old version. Remove support for it.

2025-07-23wifi: iwlwifi: mld: avoid outdated reorder buffer head_snAvraham Stern
If no frames are received on a queue for a while, the reorder buffer head_sn may be an old one. When the next frame that is received on that queue and buffered is a subframe of an AMSDU but not the last subframe, it will not update the buffer's head_sn. When the frame release notification arrives, it will not release the buffered frame because it will look like the notification's NSSN is lower than the buffer's head_sn (because of a wraparound). Fix it by updating the head_sn when the first frame is buffered.

When fips_enabled is set, keys will not be given to the hardware by mac80211 since the hardware isn't certified.

Disable features: - WoWLAN since no keys etc. - MFP since some frames need to be handled in firmware - EHT/6GHz since MFP is required Also restrict A-MSDU size since A-MSDUs cannot be split up by hardware and thus need to fit into the RX buffers in one piece.
