    Thanks Pavel for this work.
    This is what we think is the better implementation for eventfd
    proxy, in
    our last review.
    Could you add an additional patch to remove the old implementation?

I'm not really sure if we should do it -- imagine upgrading from one
version of DPDK to another.
Given the current implementation there is a backward compatibility.
I couldn't image the case any one would run old dpdk app with the new
dpdk module. However I am ok you leave it here, :), we could remove this
in next release.
Could you finish rebasing the patch before end of next week, otherwise
it will lose chance of being merged.

    Again, please run checkpatch.pl <http://checkpatch.pl> against
    your patch.

Oops. Thanks for pointing out.

    0 could be valid fd. Change it to:

        if (eventfd_link >= 0)
    Change elsewhere if i miss it.
