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 type 5 is the only one 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.
