In order to connect to networks which require 802.11w, add the MFP_CAPABLE flag and let mac80211 do the actual crypto in software. When a robust management frame is received, rx_dec->swdec is not set, even though the HW did not decrypt it. Extend the check and don't set RX_FLAG_DECRYPTED for these frames in order to use SW decryption. Use the security flag in the RX descriptor for this purpose, like it is done in the rtw88 driver.

This reverts commit 77f5924f. There is a more elegant solution to check for not decrypted frames, which is to check the security flag in the RX descriptor. Revert commit 77f5924f ("wifi: rtl8xxxu: enable MFP support") in favor of this to be able to send it to stable. Signed-off-by:

Driver throws messages when scanning with a lot of traffic, because packets in TX buffer can not be transmitted in time. Since this is a common occurrence, change them to debug message with special debug mask that developers can turn on this mask by default for further analysis.

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:

Don't subtract 1 from the power index. This was added in commit 2fc0b8e5 ("rtl8xxxu: Add TX power base values for gen1 parts") for unknown reasons. The vendor drivers don't do this. Also correct the calculations of values written to REG_OFDM0_X{C,D}_TX_IQ_IMBALANCE. According to the vendor driver, these are used for TX power training. With these changes rtl8xxxu sets the TX power of RTL8192CU the same as the vendor driver. None of this appears to have any effect on my RTL8192CU device. Cc: stable@vger.kernel.org Signed-off-by:

According to BIOS configuration of Realtek ACPI DSM function 7, RTW89_ACPI_DSM_FUNC_6GHZ_SP_SUP, we handle the regd policy of 6 GHz SP. If BIOS indicates to override driver settings, we only allow the countries, which are enabled by BIOS, to use 6 GHz SP power. Other countries will be applied to select default power when recalculating 6 GHz regulatory power selection. Signed-off-by:

The DMA channel of firmware command doesn't use TX WD (WiFi descriptor), so don't need to consider number of TX WD as factor of TX resource. Otherwise, during pause state (a transient state to switch to/from low power mode) firmware commands could be dropped and driver throws warnings suddenly: rtw89_8852ce 0000:04:00.0: no tx fwcmd resource rtw89_8852ce 0000:04:00.0: failed to send h2c The case we met is that driver sends RSSI strength of firmware command at RX path that could be running concurrently with switching low power mode. The missing of this firmware command doesn't affect user experiences, because the RSSI strength will be updated again after a while. The DMA descriptors of normal packets has three layers like: +-------+ | TX BD | (*n elements) +-------+ | | +-------+ +-> | TX WD | (*m elements) +-------+ | | +--------+ +-> | SKB | +--------+ And, firmware command queue (TXCH 12) is a special queue that has only two layers: +-------+ | TX BD | (*n elements) +-------+ | | +------------------+ +-> | firmware command | +------------------+ Fixes: 4a29213c ("wifi: rtw89: pci: correct TX resource checking in low power mode") Cc: stable@vger.kernel.org Signed-off-by:

Currently, for each completion, we check the number of descriptor queue and take it via mlxsw_pci_{sdq,rdq}_get(). This is inefficient, the DQ should be the same for all the completions in CQ, as each CQ handles only one DQ - SDQ or RDQ. This mapping is handled as part of DQ initialization via mlxsw_cmd_mbox_sw2hw_dq_cq_set(). Instead, as part of DQ initialization, set DQ pointer in the appropriate CQ structure. When we handle completions, warn in case that the DQ number that we expect is different from the number we get in the CQE. Call WARN_ON_ONCE() only after checking the value, to avoid calling this method for each completion. Signed-off-by:Amit Cohen <amcohen@nvidia.com> Reviewed-by:

Currently, for each interrupt we call mlxsw_pci_cq_count() to determine the number of CQs. This call makes additional two function's calls. This can be removed by storing this value as part of structure 'mlxsw_pci', as we already do for number of SDQs. Remove the function and __mlxsw_pci_queue_count() which is now not used and store the value instead. Signed-off-by:

The number of SDQs is stored as part of 'mlxsw_pci' structure. In some cases, the driver uses this value and in some cases it calls mlxsw_pci_sdq_count() to get the value. Align the code to use the stored value. This simplifies the code and makes it clearer that the value is always the same. Rename 'mlxsw_pci->num_sdq_cqs' to 'mlxsw_pci->num_sdqs' as now it is used not only in CQ context. Signed-off-by:

Completion queues are used for completions of RDQ or SDQ. Each completion queue is used for one DQ. The first CQs are used for SDQs and the rest are used for RDQs. Currently, for each CQE (completion queue element), we check 'sr' value (send/receive) to know if it is completion of RDQ or SDQ. Actually, we do not really have to check it, as according to the queue number we know if it handles completions of Rx or Tx. Break the tasklet into two - one for Rx (RDQ) and one for Tx (SDQ). Then, setup the appropriate tasklet for each queue as part of queue initialization. Use 'sr' value for unlikely case that we get completion with type that we do not expect. Call WARN_ON_ONCE() only after checking the value, to avoid calling this method for each completion. A next patch set will use NAPI to handle events, then we will have a separate poll method for Rx and Tx. This change is a preparation for NAPI usage. Signed-off-by:

The device supports two event queues. EQ0 is used for command interface completion events. EQ1 is used for completion events of RDQ or SDQ. Currently, for each EQE (event queue element), we check the queue number and handle accordingly. More than that, for each interrupt we schedule tasklets for both EQs. This is really ineffective, especially because of the fact that EQ0 is used only as part of driver init/fini, when EMADs are not available. There is no point to schedule the tasklet for it and check each EQE. A previous patch changed the code to poll command interface for each use of it. It means that now there is no real reason to use EQ0, as we poll the command interface. Initialize only one event queue and use it as EQ1 (this is determined by queue number). Then, for each interrupt we can schedule the tasklet only for one queue and we do not have to check the queue number. This simplifies the code and should improve performance. Note that polling command interface is ok as we use it only as part of driver init/fini. Signed-off-by:

Currently we use MLXSW_PCI_EQS_COUNT event queues. A next patch will change the driver to initialize only EQ1, as EQ0 is not required anymore when we poll command interface. Rename the macro to MLXSW_PCI_EQS_MAX as later we will not initialize the maximum supported EQs, this value represents the maximum and a new macro will be added to represent the actual used queues.

Command interface is used for configuring and querying FW when EMADs are not available. During the time that the driver sets up the asynchronous queues, it polls the command interface for getting completions. Then, there is a short period when asynchronous queues work, but EMADs are not available (marked in the code as nopoll = true). During this time, we send commands via command interface, but we do not poll it, as we can get an interrupt for the completion. Completions of command interface are received from HW in EQ0 (event queue 0). The usage of EQ0 instead of polling is done only 4 times during initialization and one time during tear down, but it makes an overhead during lifetime of the driver. For each interrupt, we have to check if we get events in EQ0 or EQ1 and handle them. This is really ineffective, especially because of the fact that EQ0 is used only as part of driver init/fini. Instead, we can poll command interface for each call of cmd_exec(). It means that when we send a command via command interface (as EMADs are not available), we will poll it, regardless of availability of the asynchronous queues. This will allow us to configure later only EQ1 and simplify the flow. Remove 'nopoll' indication and change mlxsw_pci_cmd_exec() to poll till answer/timeout regardless of queues' state. For now, completions are handled also by EQ0, but it will be removed in next patch. Additional cleanups will be added in next patches. Signed-off-by:

The structure 'mlxsw_pci_queue' stores several counters which were consumed via debugfs. Since commit 9a32562b ("mlxsw: Remove debugfs interface"), these counters are not used. Remove them. This makes the 'union u' and 'struct eq' redundant. Maintain 'struct cq' as it will be extended later. Replace increasing 'q->u.eq.ev_other_count' with WARN_ON_ONCE(), as it is used in an unreasonable case of receiving event in EQ which is not EQ0 or EQ1. When the queues are initialized, we check number of event queues and fail with the print "Unsupported number of queues" in case that the driver tries to initialize more than two queues.

Currently, as part of mlxsw_pci_cq_tasklet(), we check if any item was handled, and only in such case we arm doorbell. This is unlikely case, as we schedule tasklet only for CQs that we get an event for them, which means that they contain completions to handle. Remove this check, which is supposed to be true always, and even if it is false, it is not a mistake to ring the doorbell. We can warn on such case, but it is not really worth to add a check which will be run for each CQ handling when we do not expect to reach it and it does not point to logic error that should be handled.
