We have a rockchip rk3328 board with an 8821cs chip connected via SDIO.
Well, cs impiles SDIO, cu is USB variant.
Normally thinks work quite well for use but we do not get AP mode to
work.
We use 6.5.13 kernel with our customized DT and the in kernel 8821cs
driver:
rtw88_8821cs 12288 0
onboard_usb_hub 12288 0
rtw88_8821c 81920 1 rtw88_8821cs
crct10dif_ce 12288 1
rtw88_sdio 24576 1 rtw88_8821cs
rtw88_core 167936 2 rtw88_8821c,rtw88_sdio
mac80211 929792 2 rtw88_sdio,rtw88_core
libarc4 12288 1 mac80211
cfg80211 921600 2 rtw88_core,mac80211
We tried with wpa_cli and hostapd but to no avail.
I tried hostapd with wlan0 and eth0 bridged into br0, the SSID appears
in the wlan search results in other devices, connectig _seems_ to work
but getting an IP is not possible.
What my colleauge and me especially noticed, the TX counter for the
wlan0 interface in this use case runs, RX stays at 0:
br0 Link encap:Ethernet HWaddr 4A:86:7D:63:5C:59

In order to provide useful debug information, what should I look into?
Is it a known issue or should AP mode work flawlessly with those
drivers, which implies I forgot something.
When I use my software with an external USB WLAN stick with another
driver, exchange all wlan0 by wlan1 occurences only:
rtl8xxxu 192512 0
rtl8192cu 81920 0
rtl_usb 16384 1 rtl8192cu
rtl8192c_common 65536 1 rtl8192cu
rtlwifi 118784 3 rtl8192c_common,rtl_usb,rtl8192cu
the software AP works immediately.
