To meet this expectation, some drivers may need to group multiple discrete hardware each acting as a link in MLO under single wiphy. With this series, the bands and supported frequencies of each individual radio are reported to user space. This allows user space to figure out the limitations of what combination of channels can be used concurrently. Each mac80211 channel context is assigned to a radio based on radio specific frequency ranges and interface combinations. This is loosely based on Karthikeyan Periyasamy's series "[PATCH 00/13] wifi: Add multi physical hardware iface combination support" with some differences: - a struct wiphy_radio is defined, which holds the frequency ranges and a full struct ieee80211_iface_combination array - a channel context is explicitly assigned to a radio when created - both global and per-radio interface combination limits are checked and enforced on channel context assignment Changes since RFC: - replace static per-radio number of channels limit with full ifcomb checks - remove band bitmask in favor of only using freq rangesWhat about handling 2 GHz + 5 GHz issue we discussed in v1 related to radar detection width and num chan ctx? Is that taken care?
Seems that I missed that one. I will take care of it in the next version. Thanks, - Felix
