I don't know about this being a fair request. From what I can tell, the mere existence of DPDK enabled OVS doesn't _require_ that one is using DPDK interfaces. I haven't seen a performance impact using DPDK enabled OVS.

I don't like this approach; have a complete separate spec just for linking with a library seems like not a good approach. Of the two, I like the first more, but I'm still thinking "Are there really folks who care about -ldpdk"? Hopefully they see this message and let me know what I'm not understanding. > Another question is static versus shared linking. > > My opinion is that we should go with (1), shared linked, but I don't > know if it covers all use-cases. I agree - preference is shared linkage. I know this can create a possible issue where DPDK ABI goes out of sync - that will need to be managed carefully. However, I think it's the _right_ approach because in cases where ABI is compatible, it allows really easy upgrading without requiring a complete ovs rebuild. In cases where it isn't... well shared vs. static is a small fish. > Thoughts? > Thanks, > fbl > > > > _______________________________________________ > dev mailing list > dev@openvswitch.org > http://openvswitch.org/mailman/listinfo/dev _______________________________________________ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
