This attribute specifies whether VNS will use the loadSharing
feature. If its value is disabled, VNS will send the packets from a
given source to a given destination over only one of the preferred
links in a link group. If loadSharing is enabled, VNS will send
packets of a data stream over all the preferred links in a link group.
Note that setting loadSharing to enabled may cause packets to be
misordered.
