Thank you for your reply.

Thank you very much.
I found If I enable it, the flows with flow-mask will be installed in kernel.
Otherwise, the flow with no flow-mask wil be installed.
But I could not understand how to calculate the mask should be used.
If only one NORMAL rule exists, and I enabled megaflow, when one virtual

Hey,
I would encourage you to try it yourself, using `ovs-appctl ofproto/trace`
