The MAC address is unique to the instance of the Virtual adapter. 
Adapter instance 1 would always use the same MAC address. Adapter 
instance 2 would always use the same MAC address, etc ... I'm not sure 
what your question is in reference to. If your using DHCP over IPSec, 
the local adapter MAC isn't used. Its spoofed and uses a different MAC 
value for each connection with 2.1.7. Its spoofed and uses a persistent 
MAC value in 2.2.0 because the constantly changing value was causing 
address pool exhaustion.

What problem are you trying to solve?
