Hello,

We're currently using a CYW43455 and porting brcmfmac to and Android 8.1 BSP w/ Kernel 4.9 using backports v5.4.18. We used to be using the bcmdhd driver. bcmdhd will load a 'config.txt' file that sets certain configurations that don't seem to be available in the brcmfmac driver?

This config.txt file allows us to configure things like the supported bands, bw_caps, channels etc.. for different scenarios. Specifically we would like to disable 5Ghz entirely, which we would previously accomplish by setting "band=b" in bcmdhd's config.txt.

How do we support these configurations in brcmfmac?

Thanks!

The parameters are available as netlink signals present in v5.4.18-backports/include/uapi/linux/nl80211.h. You can use a user space application such as hostapd and configure some of these parameters in hostapd.conf or wpa_supplicant.conf. Or alternatively, you can use wl commands to configure the parameters.
