10.5.8.4 Assign Address
This command assigns SMBus address. The address and command bytes are always acknowledged.
The transaction is aborted (NACKed) immediately if any of the UDID bytes is different from I210 UDID
bytes. If successful, the manageability system internally updates the SMBus address. This command
also sets the Address Resolved flag (set to true).
