I’ve updated my home’s Mikrotik to 6.6 software and I see Openflow configuration context, I surprised, really surprised again.

As developers report:

Currently RouterOS implements OpenFlow version 1.0.0 required features. Support for newer versions, optional features and switching hardware acceleration are to be added. Current implementation should be considered experimental - NOT production ready and is available for evaluation purposes. Please contact support with feature requests and bug reports.

So, hoping and waiting.
