+freebsd-arch@ Hi Meny, Can you please post the KPI/KBI analysis that you generated to some public location and provide a link here? A straight MFC would be a major break of KPI/KBI in -STABLE and the options we're looking at are: a) Ignore the breakage and let downstream consumers deal with the fallout. This obviously isn't ideal in a -STABLE branch. b) Provide compat shims to at least preserve the KPI. One challenge is that the changes include functions with the same name but different signature/behavior. See, for example, ib_create_cq in Meny's list once he publishes it. c) Have two versions of the OFED interfaces in 11-STABLE and not break existing downstream consumers at all. I've reached out to users that I know of and know will be affected. If you use OFED and FreeBSD 11 this would be a good time to weigh in with your thoughts, ideas, concerns etc..
