But missing control path. Proof of concept work will be done. That's probably a smart alternative for packet injection. What do you mean exactly by "missing control path"? > * Remove ethtool support ? That's the other part of KNI. It works only for e1000/ixgbe.

We must seriously think about a generic alternative. Either we add DPDK support in ethtool or we create a dpdk-ethtool. (or at least a library as the one in examples/). Or we do nothing and wait to have more hardware like Mellanox supporting a kernel bifurcated driver approach. > *KNI PMD > Patch is in the mail list, missing comments. If it gets some > interest/comments/acks it may go in to next release. I'm not against KNI PMD but it looks strange to add more support to an old dying approach.
