The InfoRequest() function is used to request configuration information without the assignment

the required configuration information, and DHCPv6 server responds with Reply packet containing

the information for the client. The received Reply packet will be passed to the user by

ReplyCallback function. If user returns EFI_NOT_READY from ReplyCallback, the EFI DHCPv6

the Retransmission parameter. Otherwise, the Information Request exchange process will be
