Currently wiphy level configurations like RTS threshold, TX power etc. lacks radio level get/set support and same value is applied to all radios of wiphy. Add support to parse radio id attribute and use the same to apply the configuration to corresponding radio of a multi radio wiphy. This design will not disturb the global wiphy configuration. If radio id is not passed from userspace, then the existing design of setting attribute to all the radios will hold good. Also add support to get the radio specific attributes in a multi-radio wiphy from userspace. Note: This is design proposal to extend support to set RTS threshold/tx power for each radio and get the same from the userspace and hence sent as RFC. If we agree on this design, all per-radio attributes supported in wiphy can follow this design to modify attributes for a specific radio without disturbing other radios in the wiphy. The attributes that can be handled for each radio are: NL80211_ATTR_WIPHY_FREQ NL80211_ATTR_WIPHY_ANTENNA_TX NL80211_ATTR_WIPHY_ANTENNA_RX NL80211_ATTR_WIPHY_RETRY_SHORT NL80211_ATTR_WIPHY_RETRY_LONG NL80211_ATTR_WIPHY_FRAG_THRESHOLD NL80211_ATTR_WIPHY_RTS_THRESHOLD NL80211_ATTR_WIPHY_COVERAGE_CLASS NL80211_ATTR_WIPHY_DYN_AC With this design, the new userspace designed to set/get per-radio parameters can work with both traditional and multi-radio wiphys. An alternate design is to allow multiple radios to be configured with different per-radio attributes in a single command. To achieve this, a new nested attribute can be added to hold all per-radio attributes for all the radios in multi-radio wiphy. The attributes and respective values passed from userspace (say iw) can be parsed in NL80211 and for each attribute, corresponding handlers can be called in iteration for each radio. This design will require adding an attribute indicating index of the radio along with the nested attribute to circle down the radio of interest.
