Hmm, is it possible that maybe the kernel GRE handler is now compiled as part of the kernel instead of as a module? > Anyway; I'm going to take a slightly different course of action for > Ubuntu 13.10; I have a DKMS module what now no longer crashes BUT > can't register GRE on a 3.11 kernel - which supports it natively > anyway so this feels like less of an issue. > > So the advice for Ubuntu 13.10 will be - for GRE use the native kernel > module; for anything else use the DKMS module. I agree this should work, although I'm afraid that it might be fairly confusing to users since oftentimes people don't realize there is a difference or have the wrong module loaded. _______________________________________________ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
