CCing discuss@ back.

Then, if possible, can you determine, which exact part (dp or kernel
itself) causes a misbehavior by trying 2.3.0 datapath against older
kernel on which everything worked? After that, you can drown yourself
in a whirlpool of bisection for a problematic part, ixgbe/ixgbevf may
be a bit harder to bisect due to in-kernel changes, as you may need to
recompile entire kernel for this.
