This is the write-triggered enable/disable action object for the newer, multi-instance-capable feature series, functioning identically to the original cfcFeatureCtrlAction -- writing enable or disable triggers the action, and reading it back always returns noOp. Because this object works in concert with cfcFeatureCtrlTag2 to target a specific named instance of a feature, an admin managing multiple instances of the same feature type must ensure they are setting this in the correctly-indexed table row for the specific instance intended, not just the feature type generally. Enabling one specific FEX instance out of several configured on the device requires setting this object on the table row indexed for that particular instance's tag, not a single feature-wide switch.
