Issue attempting to filter a dvs view by config.lacpGroupConfig

I'm interested in examining the LAG/LACP configuration of a DVS via a view. I'm using the vconnector.core.get_distributed_vswitch_view() to do this currently and it works if I use config as an argument to path_set, but that is a bit broad for my purposes.

dvs_view = connection.get_distributed_vswitch_view()
sets = ['config',
      # 'config.lacpGroupConfig',  Unfortunately not available.]
dvswitches = connection.collect_properties(
    view_ref=dvs_view,
    obj_type=vim.DistributedVirtualSwitch,
    path_set=sets)

I'd like to filter by config.lacpGroupConfig but that does not appear to be a valid property to filter on in the collect_properties call.

(ERROR) - (vmodl.query.InvalidProperty) {
   dynamicType = <unset>,
   dynamicProperty = (vmodl.DynamicProperty) [],
   msg = '',
   faultCause = <unset>,
   faultMessage = (vmodl.LocalizableMessage) [],
   name = u'config.lacpGroupConfig'
}

I'm curious, if this is due to VmwareDistributedVirtualSwitch object extending the DistributedVirtualSwitch, and that the former is not instantiated until after connection.collect_properties is called, or something to that affect?

Start with connection.get_distributed_vswitch_view() and connection.collect_properties(), focusing on path_set entries for DistributedVirtualSwitch. Compare the working config path with config.lacpGroupConfig and inspect the reported vmodl.query.InvalidProperty error. Done means determining whether the property is supported for this view and documenting the resulting behavior or limitation.
