OID_ATM_SUPPORTED_SERVICE_CATEGORY

The OID_ATM_SUPPORTED_SERVICE_CATEGORY OID requests an ATM miniport driver to return a list of the ATM service categories that it supports, as a proper subset of the following system-defined values:

• ATM_SERVICE_CATEGORY_CBR
  Constant Bit Rate

• ATM_SERVICE_CATEGORY_VBR
  Variable Bit Rate

• ATM_SERVICE_CATEGORY_UBR
  Unspecified Bit Rate

• ATM_SERVICE_CATEGORY_ABR
  Available Bit Rate

An ATM miniport driver must support at least the Unspecified Bit Rate service category. The returned value is a bitwise OR of all the supported service categories--for example, ATM_SERVICE_CATEGORY_UBR | ATM_SERVICE_CATEGORY_CBR.
