class mask for unsolicited response in 2.1.0

[Phillip Bergeron]

I've tried using the unsolClassMask parameter for only sending class2 data unsolicited but I still send and receive all classes unsolicited.

from my outstation code:

stackConfig.outstation.params.allowUnsolicited = true;
stackConfig.outstation.params.unsolClassMask = ClassField(ClassField::CLASS_2);

I tried similarly to set this on the master side.

Any suggestions?
