Official OFA OFED is now strictly backports from a given kernel verison, and TBH, is not widely used now that everything is included in the modern distros. The vendor 'OFEDs' remain a big pile. I'm not even sure source is proved for them.. At least it isn't readily apparent. IMHO, the vendors should not be co-opting the OFED branding, but that is a whole other topic.... Jason
