Yes, ath12k supports tri-band MLO STA. This has been validated for QCN chipsets. Not sure if this has been tested for WCN chipsets. > > 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). Vasanth
