Routine Description:

    Dumps the specified TRANSPORT_ADDRESS structure.

Arguments:

    Prefix - A character string prefix to display before each line. Used
        to make things pretty.

    Address - Points to the TRANSPORT_ADDRESS to dump.

    ActualAddress - The actual address where the structure resides on the
        debugee.

Return Value:

    None.
