We are using a CYW43455 on Android 11, linux kernel 5.10.72 (NXP BSP)
The bring-up went OK with brcmfmac driver and wpa_supplicant. We are now able to use the wlan interfrace.
However the Compatibility Test Suite (CTS) reveals that we don't have a proper Wifi HAL. There used to be a specific HAL for bcmdhd driver, but this driver has been removed from recent kernels.
Is there a recommended wifi HAL for brcmfmac driver ?
For Android, we support AHD (Android Host Driver) https://community.infineon.com/t5/Wi-Fi-Bluetooth-for-Linux/Infineon-Android-Release-2021-12-16/m-p/... which contains the required HAL support for CTS testing.
