[ 6322 ] Update the code to only accept a MAC address as a datapath id (DPID). If
one is provided and it is already assigned to a logical device then an exception
 will be raised.

VOL-500 : Allow adapters to set the datapath id using the MAC address of the OLT device.  The logical device id will use this datapath id as well
