2023-05-15wifi: rtl8xxxu: Support new chip RTL8192FUBitterblue Smith1-0/+39
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.

2023-05-05wifi: rtl8xxxu: Allow creating interface in AP modeMartin Kaistra1-0/+2
Use the sequence from the vendor driver for setting up the beacon related registers. Also set the MAC address register here, in case the MAC address for the new interface should be different from what was set in rtl8xxxu_init_device(). This happens for example with the hostapd config option "bssid".

2023-03-20wifi: rtl8xxxu: Support new chip RTL8710BU aka RTL8188GUBitterblue Smith1-0/+44
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.

2022-12-21wifi: rtl8xxxu: Support new chip RTL8188EUJes Sorensen1-2/+38
This chip is found in cheap USB devices from TP-Link, D-Link, etc. Features: 2.4 GHz, b/g/n mode, 1T1R, 150 Mbps. Chip versions older than "I cut" need software rate control. That will be in the next commit. Until then MCS7 is used for all data frames. The "I cut" chips are not supported. They require different firmware and initialisation tables. Support can be added if someone has the hardware to test it.

2022-11-04wifi: rtl8xxxu: Fix the CCK RSSI calculationBitterblue Smith1-0/+3
The CCK RSSI calculation is incorrect for the RTL8723BU, RTL8192EU, and RTL8188FU. Add new functions for these chips with code copied from their vendor drivers. Use the old code only for the RTL8723AU and RTL8192CU. I didn't notice any difference in the reported signal strength with my RTL8188FU, but I didn't look very hard either.

2022-11-04wifi: rtl8xxxu: Add central frequency offset trackingBitterblue Smith1-0/+1
According to Realtek programmers, "to adjust oscillator to align central frequency of connected AP. Then, it can yield better performance." From commit fb8517f4fade ("rtw88: 8822c: add CFO tracking"). The RTL8192CU and a version of RTL8723AU apparently don't have the ability to adjust the oscillator, so this doesn't apply to them. This also doesn't apply to the wifi + bluetooth combo chips (RTL8723AU and RTL8723BU) because the CFO tracking should only be done when bluetooth is disabled, and determining that looked complicated. That leaves only the RTL8192EU and RTL8188FU chips. I tested this with the latter.

2022-10-04wifi: rtl8xxxu: Support new chip RTL8188FUBitterblue Smith1-0/+19
This chip is found in the cheapest USB adapters, e.g. 1.17 USD with VAT and shipping from China included. It's a gen 2 chip, similar to the RTL8723BU, but without Bluetooth. Features: 2.4 GHz, b/g/n mode, 1T1R, 150 Mbps. The vendor driver rtl8188fu version 4.3.23.6_20964.20170110 [0] was used as reference. The CD shipped with the device includes a newer driver, version 5.11.5-1-g12f7cde4b.20201102, but that one couldn't complete the WPA2 key exchange thing for whatever reason.

2021-10-05rtl8xxxu: Use lower tx rates for the ack packetChris Chiu1-0/+2
According to the Realtek propritary driver and the rtw88 driver, the tx rates of the ack (includes block ack) are initialized with lower tx rates (no HT rates) which is set by the RRSR register value. In real cases, ack rate higher than current tx rate could lead to difficulty for the receiving end to receive management/control frames. The retransmission rate would be higher then expected when the driver is acting as receiver and the RSSI is not good. Cross out higer rates for ack packet before implementing dynamic rrsr configuration like the commit 4830872685f8 ("rtw88: add dynamic rrsr configuration").
