If you want to bond links together using ovs-vsctl, you will need to consult
the OVS documentation. I’m not sure whether it is compatible with running
the switch in OpenFlow mode with Mininet.

And you can write and add code to  controller (e.g. floodlight, RYU or ODL)to
support link aggregation, you should probably consult the the controller
documentation as well as the OpenFlow specification(s).
