[ovs-discuss] Sending port's logical ID via NXM_NX_REG to the controller

[Liran Schour]

I used to send in Openvswitch 1.4.0 matchable port's logical ID to the
controller via a flow that load:value->NXM_NM_REG0.
I tried to do the same on the current release 1.9.0 and failed to do so. I
also tried to pass this information via set_field:value->metadata and
failed also.
What am I doing wrong? What is the proper way now to send matchable port's
IDs to the controller.
On version 1.4.0 I used to do that with load:value->NXM_NX_REG0

Thanks,
