Thanks for v2. The patch LGTM. Acked-by: Numan Siddique <[email protected]> Can you please add a NEWS entry for this feature ? You can add my Acked-by tag in v3. @Han - Do you have any plans to take a look at this patch ? Along with other review comments, I wonder if you've any comments on the effect of this patch on hardware offloading of OVS flows.
