Quick clarification: libvnicadm provides that functionality today, and 
it can be used, in theory, to manage VNICs from any app. dladm(1M) is 
one cusumer of that library.

In the future we'd like to specify the name of a virtual interface and 
underlying NIC or virtual switch from zonecfg(1M), which would later 
result in a VNIC to be created with the desired name (with the help of 
GLDv3 vanity naming) without the need to invoke dladm(1M) separately.

Nicolas.
