hello everybody, I need to implement Auto Channel Selection for the brcmfmac driver. The chip I'm working on is a CYW43455 (BCM43455). If I understand it correctly, user space needs the dump_survey function to be supported in cfg80211_ops (The corresponding android driver supports it under the configuration option WL_SUPPORT_ACS). Some questions then: - is there any technical reason why the dump_survey function is not already implemented in brcmfmac? - it looks like that at a minimum SURVEY_INFO_NOISE_DBM should be returned into the survey_info struct. Does anybody have any hint on how to get this value, perhaps by using a brcmf_fil_xxx_yyy_get function with BRCMF_C_GET_PHY_NOISE? thank you very much Francesco
