Implementing an NDIS 6.80 driver

An NDIS 6.80 driver must follow the requirements that are defined in Implementing an NDIS 6.30 driver.

In addition, an NDIS 6.80 driver must be compliant with the following requirements:

  • An NDIS 6.80 driver must report the correct NDIS version when it registers with NDIS. Professional memberships. schrader's teaching portfolio management.

    You must update the major and minor NDIS version number in the NDIS_Xxx_DRIVER_CHARACTERISTICS structure to support NDIS 6.80. The MajorNdisVersion member must contain 6 and the MinorNdisVersion member must contain 80. This requirement applies to miniport, protocol and filter drivers. You must also update the version information for the compiler (see Compiling an NDIS 6.80 driver).

NIC drivers

For more information about compiling a NIC driver with the NetAdapterCx, see Porting NDIS miniport drivers to NetAdapterCx (Compilation settings).

Miniport, protocol, and filter drivers

The WDK for Windows 10, version 1709 supports header versioning. Header versioning makes sure that NDIS 6.80 drivers use the appropriate NDIS 6.80 data structures at compile time.

Add the following compiler settings to the Visual Studio project for your driver:

  • For a miniport driver, add NDIS680_MINIPORT=1.
  • For a filter or protocol driver, add NDIS680=1.

For information on building a driver with the Windows 10, version 1709 release of the WDK, see Building a Driver.
