    v1 v2  
    1 thats not what i mean. because ddwrt only lets qca pick PURE upper or PURE lower (primary + 2nd + 3rd + 4th) or (primary - 2nd - 3rd - 4th). channels 40, 44, 56, 60, 104, 108, 120, 124, 136, 140, 153, 157, 165 are all invalid for vht80, for the current logic used with qualcomm.

    33if we can select upper upper/lower lower/upper lower/lower upper etc like broadcom, then those channels CAN be valid too. but not in a strict pure upper or pure lower or else its out of bounds & doesnt broadcast or uses partial channels. this should be possible on qca because r7800 when 149+upper is chosen, it uses 153+155, which IS valid, yes. but its not what the radio was commanded to do, 1/10 boots it will actually use what i picked, 149(+155). having the primary on the 2nd channel (1st + primary + 3rd + 4th), this means ath10k fw & driver can do it. its doing it on its own on 149 for some reason when not told to. this also happens to qca9880 devices.
