Get UDID (General and Directed)
The general get UDID SMBus transaction supports a constant command value of 0x03
and in directed, supports a Dynamic command value equal to the dynamic SMBus
address.
If the SMBus address has been resolved (Address Resolved flag set to true), the
manageability system does not acknowledge (NACK) this transaction. If its a General
command, the manageability system always acknowledges (ACKs) as a directed
transaction.
This command does not affect the status or validity of the dynamic SMBus address or
the Address Resolved flag.
