5.3.9.4 Assign Address
This command assigns 82598EB 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 82598EB
UDID bytes. If successful, the manageability system internally updates the SMBus address. This
command also sets the Address Resolved flag (set to true).
