Description zenghui.shi 2018-01-17 04:06:42 UTC 
Description of problem:

In FFU, ovs version will be upgraded from 2.6 to latest(2.8 or 2.9) which contains latest changes for ovs-dpdk config(e.g dpdk-devargs), this will happen before overcloud minor update is executed, there is a chance that the config changes made by ovs upgrade be overwritten by overcloud minor update.

this bz is going to backport support of those ovs config changes that may be overwritten by overcloud minor update to 10.z so that the config won't be broken after overcloud minor update.
