DirectionType
A NET_IF_DIRECTION_TYPE NDIS network interface direction type.
ConnectionType
A NET_IF_CONNECTION_TYPE NDIS network interface connection type.
IfType
The Internet Assigned Numbers Authority (IANA) interface type. For example, IF_TYPE_ETHERNET_CSMACD (6) is the value for IfType that is assigned to any Ethernet-like interface. For a list if interface types, see NDIS Interface Types.

NdisPauseFunctionsReceiveOnly
Indicates that the adapter and link partner only support sending pause frames from the link partner to the adapter
NdisPauseFunctionsSendAndReceive
Indicates that the adapter and link partner support sending and receiving pause frames in both transint and receive directions.

The adapter has auto-negotiated the pause functions with the link partner.
PowerManagementCapabilitiesEx
A pointer to an NDIS_PM_CAPABILITIES structure. This structure specifies power management capabilities of the miniport adapter. This member is mandatory for NDIS 6.20 and later drivers.
Remarks
A miniport driver passes a pointer to an NDIS_MINIPORT_ADAPTER_GENERAL_ATTRIBUTES structure in the MiniportAttributes parameter of the NdisMSetMiniportAttributes function. A miniport driver calls NdisMSetMiniportAttributes from its MiniportInitializeEx function during initialization. Miniport drivers should set these attributes after they set the registration attributes in the NDIS_MINIPORT_ADAPTER_REGISTRATION_ATTRIBUTES structure and before they set any other attributes. Setting these attribute is mandatory.
