Sure, this is a driver only patch so risk is all on you and if you prefer to get it we can get it as long it doesn't break anything on rest of the DPDK. Only it would be better to address these kind of issues in early rc1 stages, instead of a few days before release. Prioritizing testing on rc1, and even sharing a brief test status result on release status meeting, as done by some other companies, would be great.
