Hi Kevin,
Latest official DPDK-16.04<http://www.dpdk.org/download> has been
released and we're trying to use OVS(v2.5.0) with this version DPDK.
However current OVS cannot support dpdk16.04 and we hit the
incompatible issue which caused OVS failed to build with dpdk16.04.
According to the failure message, corresponding code updates are also
needed in OVS to support DPDK16.04. I would like to know do we have
any plan to implement the fix/patch to support DPDK16.04?

Hi,
Yeah I was looking at this problem last night and it seems it was caused
by these DPDK commits
http://dpdk.org/browse/dpdk/commit/?id=39fd068a27237ff0f825d8efd9ba9ed9a28cacb0
http://dpdk.org/browse/dpdk/commit/?id=82113036e4e54a82ec485a05acce9a43ceb60552
I was recently told that DPDK-2.2 is still the required dependency
(http://openvswitch.org/pipermail/dev/2016-March/068441.html) but it
should be
easy enough (based on these two DPDK commits) to make OVS build against
16.04. Whether that would run normally, I don't know ;)
