Dear iwlwifi developers, I get a yellow warning in the journal: “iwlwifi 0000:b3:00.0: api flags index 2 larger than supported by driver”.

Perhaps, it's time to upgrade the driver? Or is the aforementioned yellow message a real warning for me as an admin or a user, and I should take some action? Gratefully, AlMa
