2023-05-15wifi: rtl8xxxu: Support new chip RTL8192FUBitterblue Smith9-31/+2263
This is a newer chip, similar to the RTL8710BU in that it uses the same PHY status structs. Features: 2.4 GHz, b/g/n mode, 2T2R, 300 Mbps. It can allegedly have Bluetooth, but that's not implemented here. This chip can have many RFE (RF front end) types, of which types 1 and 5 are the only ones tested. Many of the other types need different initialisation tables. They can be added if someone wants them. The vendor driver v5.8.6.2_35538.20191028_COEX20190910-0d02 from https://github.com/BrightX/rtl8192fu was used as reference, with additional device IDs taken from https://github.com/kelebek333/rtl8192fu-dkms. The vendor driver also claims to support devices with ID 0bda:a725, but that is found in some bluetooth-only devices, so it's not supported here.

2023-05-15wifi: rtl8xxxu: fix authentication timeout due to incorrect RCR valueYun Lu2-1/+4
When using rtl8192cu with rtl8xxxu driver to connect wifi, there is a probability of failure, which shows "authentication with ... timed out". Through debugging, it was found that the RCR register has been inexplicably modified to an incorrect value, resulting in the nic not being able to receive authenticated frames. To fix this problem, add regrcr in rtl8xxxu_priv struct, and store the RCR value every time the register is written, and use it the next time the register need to be modified.

The goal of writing 0x6954341e / 0x6955341e to REG_OFDM0_XA_AGC_CORE1 appears to be setting the initial gain, which is stored in bits 0..6. Bits 7..31 are the same as what the phy init tables write. Modify only bits 0..6 so that we don't have to care about the values of the others. This way we don't have to add another "else if" for the RTL8192FU.

2023-03-20wifi: rtl8xxxu: Support new chip RTL8710BU aka RTL8188GUBitterblue Smith12-62/+2481
This chip is found in cheap "free driver" USB adapters from Aliexpress. Initially they pretend to be a CD-ROM containing the driver for Windows. "Ejecting" switches the device to wifi mode. Features: 2.4 GHz, b/g/n mode, 1T1R, 150 Mbps. This chip is more unique than other Realtek chips: * The registers at addresses 0x0-0xff, which all the other chips use, can't be used here. New registers at 0x8000-0x80ff must be used instead. And it's not a simple matter of adding 0x8000: 0x2 (REG_SYS_FUNC) became 0x8004, 0x80 (REG_MCU_FW_DL) became 0x8090, etc. * Also there are a few new registers which must be accessed indirectly because their addresses don't fit in 16 bits. No other chips seem to have these. * The vendor driver compiles to 8188gu.ko, but the code calls the chip RTL8710B(U) pretty much everywhere, including messages visible to the user. Another difference compared to the other chips supported by rtl8xxxu is that it has a new PHY status struct, or three of them actually, from which we extract the RSSI, among other things. This is not unique, though, just new. The chips supported by rtw88 also use it.

2023-03-20wifi: rtl8xxxu: RTL8192EU always needs full initBitterblue Smith1-0/+1
Always run the entire init sequence (rtl8xxxu_init_device()) for RTL8192EU. It's what the vendor driver does too. This fixes a bug where the device is unable to connect after rebooting: wlp3s0f3u2: send auth to ... (try 1/3) wlp3s0f3u2: send auth to ... (try 2/3) wlp3s0f3u2: send auth to ... (try 3/3) wlp3s0f3u2: authentication with ... timed out Rebooting leaves the device powered on (partially? at least the firmware is still running), but not really in a working state.

We can use the module_usb_driver macro instead of open-coding the driver's init and exit functions. This is simpler and saves some lines of code. Other realtek wireless drivers use module_usb_driver as well.

2023-02-13wifi: rtl8xxxu: Register the LED and make it blinkBitterblue Smith2-0/+46
If the chip can have an LED, register a struct led_classdev and enable hardware-controlled blinking. When the chip is not transmitting or receiving anything the LED is off. Otherwise the LED will blink faster or slower according to the throughput. The LED can be controlled from userspace by writing 0, 1, or 2 to /sys/class/leds/rtl8xxxu-usbX-Y/brightness: 0 - solid off. 1 - solid on. 2 - hardware-controlled blinking. In this patch none of the chips advertise having an LED. That will be added in the next patches.
