Hello Yuriy,Yeah, as I commented, the common interface combination can work, and https://lore.kernel.org/all/90c806db-9d75-4c25-88f5-252da80b5d40@xxxxxxxx/ also help to verify in QCA6390.
Buff ... again the same that was already in the thread ...
As I commented, if you want to have a common interface combination, please
go ahead with yours, and then we can see on our own.
Thanks
Best regards
Jose Ignacio
