INF files for NetAdapterCx client drivers
INF files for NetAdapterCx client drivers build on top of standard network INF files, with some additional keywords specific to NetAdapterCx.
For more information about standard network INF files, see Creating Network INF Files. For more information about base INF files, see Overview of INF files.
Note: Starting in Windows 11, version 21H2, Selective Suspend keywords are deprecated and must not be used by NetAdapterCx client drivers.
The following table describes the new INF keywords in NetAdapterCx.
| New network keyword | INF file section | Optional or required | Description |
|---|---|---|---|
| *IfConnectorPresent | Device.NT | Required | A boolean value that indicates if a connector is present. Set this keyword to 1, or TRUE, if there is a physical adapter. Note Replaces the IfConnectorPresent field from the NDIS_MINIPORT_ADAPTER_GENERAL_ATTRIBUTES structure. |
| *ConnectionType | Device.NT | Required | A NET_IF_CONNECTION_TYPE value that specifies the NDIS network interface connection type. |
| *DirectionType | Device.NT | Required | A NET_IF_DIRECTION_TYPE value that specifies the NDIS network interface direction type. |
| *AccessType | Device.NT | Required | A NET_IF_ACCESS_TYPE value that specifies the NDIS network interface access type. |
| *HardwareLoopback | Device.NT | Required | A boolean value that indicates if the network interface card (NIC) has hardware loopback support. Note Setting this keyword to 1, or TRUE, is the equivalent of not setting the NDIS_MAC_OPTION_NO_LOOPBACK flag in the MacOptions field of the NDIS_MINIPORT_ADAPTER_GENERAL_ATTRIBUTES structure. |
| NumberOfNetworkInterfaces | Device.NT | Optional | Specifies how many network interfaces the NIC supports. Required only if the NIC supports more than one network interface per device. |
