rtw_8822cs : no AP mode ?

[chris4git]

Hi, Context : Armbian bookworm 24.11 6.6.58-current-rockchip64 After make/make install of current version of the driver (and reboot) iw list gives only managed and monitor modes available. Under Android all modes are available.

Logs : Oct 28 15:08:39 station-m2 kernel: rtw_8822cs mmc1:0001:1: WOW Firmware version 9.9.4, H2C version 15 Oct 28 15:08:39 station-m2 kernel: rtw_8822cs mmc1:0001:1: Firmware version 9.9.15, H2C version 15

Something necessary at compilation time to activate AP mode ?

Yes, you need to make this change:

    int max_tx_headroom = 0;
    int ret;

SDIO (and USB) devices had some problems with AP mode, so someone decided that AP mode should be disabled until the problems are fixed. It's very possible that the problems are all fixed now. People with USB devices reported that it's working better. I don't know if anyone tested the SDIO side.

Thanks @dubhater ! Now all modes are present. Next step : to get a working setup with armbian-config...
