or not vc-vlan-type forwarding is forced in the data-path when

pwTemplateForceVlanVcForwarding is set to 'true', vc-vlan-type
forwarding is forced.
An 'inconsistentValue' error is returned when an attempt is
made to set the value of pwTemplateForceVlanVcForwarding
to 'true' and pwTemplateVcType is not set to 'ether'.
