Documentation     Test MIB Template handling of ONU Go adapter
...               with BBSIM controlledActivation: only-onu only!
...               Set up BBSIM with 'onu=2' (as well as 'pon=2') and 'controlledActivation=only-onu' e.g. with Extra Helm Flags!
...               Run robot with bbsim-kind-2x2.yaml (needed for test case ONU MIB Template Data Test)
...               For test cases Unknown ME/Attribute bbsim-kind.yaml would work too.
...               For Unknown ME set up BBSIM with injectOmciUnknownME=true e.g. with Extra Helm Flags!
...               For Unknown Attribute set up BBSIM with injectOmciUnknownAttributes=true e.g. with Extra Helm Flags!
