This has been validated for QCN chipsets. > Not sure if this has been tested for WCN chipsets. Can this work with some combination of Compex radios in an x86 chassis, or does it require some integrated AP style platform? If x86 is supported, please suggest some radio model(s) you think will work. >> Or is ath12k entirely DBDC at this point with no tri-band MLO capability? >> >> In addition, back in ath10k days, I was able to get the radio to do up to >> 64 STA vdevs once I put the firmware on a diet.  From a quick look at the ath12k >> driver, it seems the limit for STA vdevs is exactly 1.  Is there any somewhat-documented >> way to get ath12k to support more STA vdevs? > > Supporting more number of STA vdevs instead of the current 1 STA will require > firmware changes (and of course more validations). Any idea if QCA is offering ath12k FW source under NDA and/or for some price? We could likely make the changes and validate, but we need the FW source and a toolchain to compile it.
