Clear bit 8 of REG_SYS_STATUS1 after MAC power on. Without this, some RTL8821CU and RTL8811CU cannot connect to any network: Feb 19 13:33:11 ideapad2 kernel: wlp3s0f3u2: send auth to 90:55:de:__:__:__ (try 1/3) Feb 19 13:33:13 ideapad2 kernel: wlp3s0f3u2: send auth to 90:55:de:__:__:__ (try 2/3) Feb 19 13:33:14 ideapad2 kernel: wlp3s0f3u2: send auth to 90:55:de:__:__:__ (try 3/3) Feb 19 13:33:15 ideapad2 kernel: wlp3s0f3u2: authentication with 90:55:de:__:__:__ timed out The RTL8822CU and RTL8822BU out-of-tree drivers do this as well, so do it for all three types of chips.
