OID_ATM_SUPPORTED_AAL_TYPES
The OID_ATM_SUPPORTED_AAL_TYPES OID requests an ATM miniport driver to return a list of the AAL types that it supports, as a proper subset of the following system-defined values:
AAL_TYPE_AAL0
AAL0AAL_TYPE_AAL1
AAL1AAL_TYPE_AAL34
AAL34AAL_TYPE_AAL5
AAL5
The returned value is a bitwise OR of all the AAL supported types--for example, AAL_TYPE_AAL0 | AAL_TYPE_AAL5.
