By the way, it does not apply cleanly, so it needs to be rebased on top of the up-to-date wireless-drivers-next tree. Let me know if you would prefer me to care about rebase. Then I will add this patch to the upcoming series of qtnfmac fixes. Reviewed-by: Sergey Matyukevich <sergey.matyukevich.os@xxxxxxxxxxxxx> Regards, Sergey
