Hi John, Thanks a lot. It helps. I backported the changes to 11.2 and tried booting in my board with success without any need for the said tunables. I see those changes are marked for MFC after 2 Weeks. But I don't see them still in stable/11 branch. So, will it be taken into stable/11 branch by any chance? If not, can the backported changes be submitted for review to take into stable/11 branch?
