Hi Richael, thanks for the quick re-spin.
Although this shows a build error in patchwork, as we know, that's
because of the depenedent patch set -
http://patches.dpdk.org/project/dpdk/list/?series=17453
<http://patches.dpdk.org/project/dpdk/list/?series=17453>
If I apply that dependency first, it then builds fine, and checkpatch is
clean, although I can't give it a run, as I currently don't have access
to a suitable machine. LGTM.
