  If the DEBUG_PROPERTY_DEBUG_ASSERT_ENABLED bit of PcdDebugProperyMask is clear, \r

  If the DEBUG_PROPERTY_DEBUG_ASSERT_ENABLED bit of PcdDebugProperyMask is set,  \r
  The Signature field of the data structure ISCSI_FORM_CALLBACK_INFO \r
  is compared to TestSignature.  If the signatures match, then a pointer \r
