Since there was no other response I'll try to wrap up. Yes #1 also is my preferred solution at the moment. We tried with individual following the tracking of LIBABIVER upstream but as outlined before we hit too many issues. I discussed it in the deb_dpdk group which acked as well to use this as general approach. The other options have too obvious flaws as I listed on my initial report and - thanks btw - you added a few more. @Bruce - sorry I don't think dropping config options is the solution. Yet my suggestion does not prevent you from doing so. > You could easily do this independently of us upstream > fixing the ABI problems. I agree, but I'd like to suggest the mechanism I want to implement. An ack by upstream for the Feature to set such a major ABI would be great. Actually since it is optional and can help more people integrating DPDK getting it accepted upstream be even better. I'll send a patch in reply to this thread later today that implements what I have in mind. -- Christian Ehrhardt Software Engineer, Ubuntu Server Canonical Ltd
