When 'sscanf()' is not needed to scan an input, prefer common 'kstrtoX_from_user()' over 'rtw_debugfs_copy_from_user()' with following 'kstrtoX()'. Minor adjustments, compile tested only. Signed-off-by:

The CSA countdown in the beacon frames, which are sent out by firmware, needs to get updated by the driver. To achieve this, convert update_beacon_work to delayed_work and schedule it with the beacon interval in case CSA is active and the countdown is not complete. Signed-off-by:

Currently rtl_usb performs register writes using the async usb_submit_urb() function. This appears to work fine for the RTL8192CU, but the RTL8192DU (soon to be supported by rtlwifi) has a problem: it transmits everything at the 1M rate in the 2.4 GHz band. (The 5 GHz band is still untested.) With this patch, rtl_usb performs the register writes using the synchronous usb_control_msg() function, and the RTL8192DU works normally. The RTL8192CU still works. The vendor drivers use the async writes in only one function, rtl8192du_trigger_gpio_0 / rtl8192cu_trigger_gpio_0, which probably doesn't even run in real life. They use sync writes everywhere else. Also, remove "sync" and "async" from the names of the members of struct rtl_io to avoid confusion: write{8,16,32}_async -> write{8,16,32} read{8,16,32}_sync -> read{8,16,32} Signed-off-by:Bitterblue Smith <rtl8821cerfe2@gmail.com> Acked-by:

The firmware of coming WiFi 7 chips can support more AP functions, like virtual AP, so extend format of download beacon frame to configure them. Currently rtw89 only enables AP mode as old chips, so leave new fields zeros. Signed-off-by:

Download beacon frame via H2C command for AP mode, and then firmware can issues beacon periodically. Originally TIM offset minus fixed 24 bytes of frame header implicitly in macro, and this patch explicitly uses ieee80211_hdrlen() to get header length, but expected to change nothing at all.

New H2C command is introduced to pause/sleep transmitting. That extends more bits to support more MAC ID, and currently we still configure 256 MAC ID at most. This new command is always used by coming WiFi 7 chips, and existing chips can use old or new command because firmware still preserves the old one. Add a firmware feature flag to determine which command is adopted according to firmware version. Signed-off-by:

bcm4331 seems to not function correctly with QoS support. This may be due to issues with currently available firmware or potentially a device specific issue. When queues that are not of the default "best effort" priority are selected, traffic appears to not transmit out of the hardware while no errors are returned. This behavior is present among all the other priority queues: video, voice, and background. While this can be worked around by setting a kernel parameter, the default behavior is problematic for most users and may be difficult to debug. This patch offers a working out-of-box experience for bcm4331 users.

rtl8xxxu_set_basic_rates() sets the wrong initial RTS rate. It sets the next higher rate than the one it should set, e.g. 36M instead of 24M. The while loop was supposed to find the index of the most significant bit which is 1, but it was copied incorrectly from the vendor driver. Use __fls() instead. Signed-off-by:

Some devices, like the Comfast CF-826F, use LED1, which already works. Others, like Asus USB-N13 C1, use LED0, which doesn't work correctly. Write the right values to the LED control registers to make LED0 work as well. This is unfortunately tested only with the Comfast CF-826F. Signed-off-by:

Everything is in place now for concurrent mode, we can tell the system that we support it. We will allow a maximum of 2 virtual interfaces, one of them can be in AP mode. Signed-off-by:

When the driver is used for concurrent mode, both virtual interfaces can be set to station or AP mode, though only one can be in AP mode at the same time. In order to keep the code simple, use only hw port 0 for AP mode. When an interface is added in AP mode which would be assigned to port 1, use a switch_port function to transparently swap the mapping between virtual interface and hw port. Signed-off-by:

Add a custom function for allocating entries in the sec cam. This allows us to store multiple keys with the same keyidx. The maximum number of sec cam entries for 8188f is 16 according to the vendor driver. Add the number to rtl8xxxu_fileops, so that other chips which might support more entries, can set a different number there. Set the bssid as mac address for group keys instead of just using the ethernet broadcast address and use BIT(6) in the sec cam ctrl entry for differentiating them from pairwise keys like in the vendor driver. Add the TXDESC_EN_DESC_ID bit and the hw_key_idx to tx broadcast/multicast packets in AP mode. Finally, allow the usage of rtl8xxxu_set_key() for AP mode. Signed-off-by:

Until now, the driver only assigned a dedicated macid for connections made in AP mode, in STA mode the return value of rtl8xxxu_get_macid() was simply 0. To differentiate between port 0 and 1, when both are in STA mode, allocate a second macid (with value 1) and set sta_info->macid according to the used port_num in rtl8xxxu_sta_add(). Signed-off-by:

Call set_linktype and set_bssid now with correct port_num. Call stop_tx_beacon only for port 0, as we don't support beacons on port 1. Explicit changes to BEACON will only happen for AP type interfaces, so we don't need an additional check there. Signed-off-by:

Add a custom struct to store in vif->drv_priv with a reference to port_num and fill it when a new interface is added. Choose a free port_num for the newly added interface. As we only want to support AP mode/sending beacons on port 0, only change the beacon settings if a new interface is actually assigned to port 0. Call set_linktype() and set_mac() with the appropriate port_num. Signed-off-by:

As we only want to support AP mode/sending beacons on port 0, change from priv->vif to priv->vifs[0] in the check for AP mode. Additionally, if we are in AP mode, don't filter RX beacon and probe response frames to still allow working STATION mode on the other interface. Signed-off-by:

In concurrent mode supported by this driver, both interfaces will use the same channel and same wireless mode. It is therefore possible to get the wireless mode by checking the first connected interface. Signed-off-by:

To prepare for concurrent mode, enhance rtl8xxxu_set_bssid() to write the BSSID of the respective interface to REG_BSSID or REG_BSSID1. Like done with rtl8xxxu_set_mac(), call rtl8xxxu_set_bssid() with port_num = 0, until the callers also support multiple interfaces. Signed-off-by:

There are multiple places in the code where the current connection status of wifi is checked. The driver will support two interfaces soon and either one of them (or both) could be connected. Convert all uses of (vif && vif->cfg.assoc) to a new helper function rtl8xxxu_is_assoc() which checks both interfaces. Signed-off-by:

To prepare for concurrent mode, enhance rtl8xxxu_set_mac() to write the mac address of the respective interface to REG_MACID or REG_MACID1. Remove the call to rtl8xxxu_set_mac() from the init function as we set it in rtl8xxxu_add_interface() later anyway. Until rtl8xxxu_add_interface() can handle both interfaces, call rtl8xxxu_set_mac() with port_num = 0. Signed-off-by:
