We construct EAPoL packet with various encryption method, and download to firmware. Also we add Key Encryption Key (KEK) and Key Confirmation Key (KCK) to H2C command. Once firmware received EAPoL group rekey packet(1/2) can TX EAPoL group rekey packet(2/2) when suspend. Signed-off-by:

We will support MLO on 802.11be chip, e.g. RTL8922A, in the future. At that time being, we will set WIPHY_FLAG_SUPPORTS_MLO according to chip info and FW features at runtime. But, with WIPHY_FLAG_SUPPORTS_MLO flag, cfg80211 will disable WEXT. In case inconsistent user experience, if 802.11be chip, we disable WEXT uniformly from now on. Signed-off-by:

Originally, we have an ACPI function to determine whether to enable UNII-4. Since IC (Industry Canada) has allowed UNII-4, the ACPI result is extended to be two bits as below. * BIT(0): determine if rtw89_regd::FCC enable UNII-4 * BIT(1): determine if rtw89_regd::IC enable UNII-4 Besides, to take old platforms into account, we enable UNII-4 on IC if and only if BIOS configuration enable it.

Since WiFi 7 is expected to support MLO, so we should enable MAC-0/1 and PHY-0/1. By default, set dbcc_en=true, change quota to DBCC mode, and set MLO mode to 2 + 0 that means we only use 2x2 connection on MAC/PHY-0 for now. Signed-off-by:

After MLO, we will need to consider not only active chanctx but also active interfaces (roles) to decide entity things. So in advance, we move handling from chanctx_ops::add/remove to chanctx_ops::assign_vif/unassign_vif. Then, we can recalculate and aware active interfaces' changes. For now, behavior should not be really different, since active chanctx and active interface are one-to-one mapping before MLO. Signed-off-by:

Some of our calculation during concurrent mode depend on last beacon TSF. Originally, we just set IEEE80211_HW_TIMING_BEACON_ONLY and get what we want from mac80211. But, IEEE80211_HW_TIMING_BEACON_ONLY will be restricted once we declare MLO. Since we are about to consider the MLO stuffs, so sync beacon TSF by ourselves now and unset IEEE80211_HW_TIMING_BEACON_ONLY. Signed-off-by:

There are still surprisingly many non-chanctx drivers, but in mac80211 that code is a bit awkward. Simplify this by having those drivers assign 'emulated' ops, so that the mac80211 code can be more unified between non-chanctx/chanctx drivers. This cuts the number of places caring about it by about 15, which are scattered across - now they're fewer and no longer in the channel context handling.

The RF calibrations are moved into firmware, so we trigger calibrations by H2C commands and wait for C2H completion events. However, these events can be received only after HCI (i.e. PCI for now) starts, so we should do initial RF calibrations after that. Signed-off-by:

Ping-Ke Shih authored
The RF calibrations should be executed one by one, so add a completion to ensure one is finish before next. The report from C2H event contains state and optional version, and we only check the state for now. We also care about the time a RF calibration takes, so record start time before asking firmware to do calibration and get the delta time when receiving report. Consider SER recovery, we can't receive C2H event, use half of argument 'ms' as fixed delay that is 2 times of measured maximum time of calibrations. Signed-off-by:

The chip_ops::bb_preinit and ::bb_postinit are called before and after loading BB parameters from tables of firmware file. The ::bb_reset is used to reset hardware state, and currently it is not needed by 8922AE so leave it as empty. The ::bb_sethw is to implement conditional parameters. Signed-off-by:

WiFi 7 chips can operate in various MLO applications, such as 1 link (2SS) and 2 links (1SS + 1SS), and we should configure different PHY mode for each of them. For example, - MLO_2_PLUS_0_1RF is 1 link with 2SS rate, and enable one RF component. - MLO_1_PLUS_1_1RF is 2 links with 1SS rate for each, and enable one RF component that can support two paths. By default, we set the mode to legacy MLO_DBCC_NOT_SUPPORT (don't support MLO and DBCC yet), and later we will introduce logic to change the mode. Signed-off-by:

According to IEEE Std. 802.11, it defines: Indicates whether the STA is capable of interpreting the Extended NSS BW Support subfield of the VHT Capabilities Information field.

We add a scanning check to avoid entering IPS after ROC (remain on channel) during scanning. Additionally, When P2P scanning, the flow is `1. p2p_listen step` and `2. configure filter` and `3. p2p_scan starts` in wpas, but in kernel, cfg80211 uses another workqueue to notify driver the filter change, so sometimes we see (1 > 3 > 2), that will cause Rx filter related to scan to be cleared. Therefore, we add a scanning check when configure filter to avoid scan results to be filtered. Finally, we cancel the ROC delayed workqueue before entering ROC to avoid entering twice, which might cause leaving ROC too early. Signed-off-by:

Add dynamic mechanism EDCCA (Energy Detection Clear Channel Assessment) in track work. Using a fixed-value threshold will make EDCCA particularly sensitive and cause failure to transmit under certain circumstances. Therefore, the threshold is dynamically adjusted to make EDCCA suitable for any situation. However, in some cases, we will adjust the EDCCA threshold to the highest level so that urgent transmissions can be performed successfully, such as scanning. Finally, in order to observe the EDCCA report in time, add the EDCCA perIC register macro and EDCCA HW report analysis. EDCCA logs can be displayed by using the EDCCA debug mask. Signed-off-by:

For WiFi 7 chips, some fields and predefined length are changed, so add them accordingly. The mac_id field is used to identify peer that send a packet, and we can use it to know RSSI and traffic from the peer. For WiFi 7 chips, RXWD.mac_id of PPDU status packet is not set by hardware. Instead, we should fill it by rxinfo_user[].mac_id of PPDU status content. Also, filter out invalid reports to prevent warning messages keep showing. Signed-off-by:

We currently have napi_if_scheduled_mark_missed that can be used to check if napi is scheduled but that does more thing than simply checking it and return a bool. Some driver already implement custom function to check if napi is scheduled. Drop these custom function and introduce napi_is_scheduled that simply check if napi is scheduled atomically. Update any driver and code that implement a similar check and instead use this new helper. Signed-off-by:
