When there's not going to be any data in the data event, we don't need to add it at all (unlike the TX version, it has no data at all.) Also combine the tracing into a separate inline so we only call iwl_rx_trace_len() once, which also simplifies things, and lets us have a single place to later add other checks. Signed-off-by:

Current handling of del pmksa with SSID is limited to FILS security. In the current change the del pmksa support is extended to SAE/OWE security offloads as well. For OWE/SAE offloads, the PMK is generated and cached at driver/FW, so user app needs the capability to request cache deletion based on SSID for drivers supporting SAE/OWE offload. Signed-off-by:

To support the WBRF mechanism, Wifi adapters utilized in the system must register the frequencies in use (or unregister those frequencies no longer used) via the dedicated calls. So that, other drivers responding to the frequencies can take proper actions to mitigate possible interference. Co-developed-by:

Due to electrical and mechanical constraints in certain platform designs there may be likely interference of relatively high-powered harmonics of the (G-)DDR memory clocks with local radio module frequency bands used by Wifi 6/6e/7. To mitigate this, AMD has introduced a mechanism that devices can use to notify active use of particular frequencies so that other devices can make relative internal adjustments as necessary to avoid this resonance.

To diagnose the reason why firmware or hardware get abnormal, add to dump MAC registers related to counters and interrupt masks. With these values, people can classify problems and check if registers values are unexpected, and then correct them. However, it could possible false alarm because firmware triggers this SER event by wrong conditions that we should correct it at firmware or register settings. In field, SER might happen under special conditions, and very hard to happen again, so dump lots of registers to provide rich information to catch the problem. Signed-off-by:

Besides, RTL8922A sync address offset of reserved payload engine. And, SER (system error recovery) tweaks conversion from WCPU address to indirect access address for RTL8922A. The new conversion works for all supported chips. Signed-off-by:

In concurrent mode, when STA interface is scanning, it causes AP interface TX beacon on wrong channel. We modified it to scan with the operating channel when one of the interfaces is already connected. Additionally, STA interface need to stop scan when AP interface is starting to avoid TX beacon on wrong channel. Finally, AP interface need to stop TX beacon when STA interface is scanning and switching to non-OP channel,This prevent other device to get beacons on wrong channel. Signed-off-by:

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:

The rtlwifi driver comes with a number of PCI related defines that are unused and many would be provided by PCI core anyway if they'd be needed again. Similarly, the struct rtl_pci_capabilities_header is unused and no driver should come up their own way to access PCI Capabilities anyway. Remove the unused/duplicated PCI related defines and struct.

The rtlwifi driver comes with custom code to write into PCIe Link Control register. RMW access for the Link Control register requires locking that is already provided by the standard PCIe capability accessors. Convert the custom RMW code writing into LNKCTL register to standard RMW capability accessors. The accesses are changed to cover the full LNKCTL register instead of touching just a single byte of the register.

Ever since introduction in the commit 0c817338 ("rtl8192ce: Add new driver") the rtlwifi code has, according to comments, attempted to disable/enable ASPM of the upstream bridge by writing into its LNKCTL register. However, the code has never been correct because it performs the writes to the device instead of the upstream bridge. Worse yet, the offset where the PCIe capabilities reside is derived from the offset of the upstream bridge. As a result, the write will use an offset on the device that does not relate to the LNKCTL register making the ASPM disable/enable code outright dangerous. Because of those problems, there is no indication that the driver needs disable/enable ASPM on the upstream bridge. As the Capabilities offset is not correctly calculated for the write to target device's LNKCTL register, the code is not disabling/enabling device's ASPM either. Therefore, just remove the upstream bridge related ASPM disable/enable code entirely. The upstream bridge related ASPM code was the only user of the struct mp_adapter members num4bytes, pcibridge_pciehdr_offset, and pcibridge_linkctrlreg so those are removed as well. Note: This change does not remove the code related to changing the device's ASPM on purpose (which is independent of this flawed code related to upstream bridge's ASPM). Suggested-by:

Lukas reports skb_over_panic errors on his Banana Pi BPI-CM4 which comes with an Amlogic A311D (G12B) SoC and a RTL8822CS SDIO wifi/Bluetooth combo card. The error he observed is identical to what has been fixed in commit e967229e ("wifi: rtw88: sdio: Check the HISR RX_REQUEST bit in rtw_sdio_rx_isr()") but that commit didn't fix Lukas' problem. Lukas found that disabling or limiting RX aggregation works around the problem for some time (but does not fully fix it). In the following discussion a few key topics have been discussed which have an impact on this problem: - The Amlogic A311D (G12B) SoC has a hardware bug in the SDIO controller which prevents DMA transfers. Instead all transfers need to go through the controller SRAM which limits transfers to 1536 bytes - rtw88 chips don't split incoming (RX) packets, so if a big packet is received this is forwarded to the host in it's original form - rtw88 chips can do RX aggregation, meaning more multiple incoming packets can be pulled by the host from the card with one MMC/SDIO transfer. This Depends on settings in the REG_RXDMA_AGG_PG_TH register (BIT_RXDMA_AGG_PG_TH limits the number of packets that will be aggregated, BIT_DMA_AGG_TO_V1 configures a timeout for aggregation and BIT_EN_PRE_CALC makes the chip honor the limits more effectively) Use multiple consecutive reads in rtw_sdio_read_port() and limit the number of bytes which are copied by the host from the card in one MMC/SDIO transfer. This allows receiving a buffer that's larger than the hosts max_req_size (number of bytes which can be transferred in one MMC/SDIO transfer). As a result of this the skb_over_panic error is gone as the rtw88 driver is now able to receive more than 1536 bytes from the card (either because the incoming packet is larger than that or because multiple packets have been aggregated). In case of an receive errors (-EILSEQ has been observed by Lukas) we need to drain the remaining data from the card's buffer, otherwise the card will return corrupt data for the next rtw_sdio_read_port() call.
