38   If the DEBUG_PROPERTY_DEBUG_ASSERT_ENABLED bit of PcdDebugProperyMask is clear,

41   If the DEBUG_PROPERTY_DEBUG_ASSERT_ENABLED bit of PcdDebugProperyMask is set,
42   The Signature field of the data structure ISCSI_FORM_CALLBACK_INFO
43   is compared to TestSignature.  If the signatures match, then a pointer
44   to the pointer to a data structure ISCSI_FORM_CALLBACK_INFO is returned.
45   If the signatures do not match, then DebugAssert() is called with a description
46   of "CR has a bad signature" and Callback is returned.
47 
48   If the data type ISCSI_FORM_CALLBACK_INFO_SIGNATURE does not contain the field
49   specified by Callback, then the module will not compile.

52   then the module will not compile.
