Summary of Changes Required to Port a Miniport Driver to NDIS 6.0

This topic summarizes the changes that are required to port an NDIS 5.x miniport driver to NDIS 6.0. Porting earlier drivers is similar to porting NDIS 5.x drivers.

To run in the NDIS 6.0 environment, NDIS 5.x miniport drivers must be modified as follows:

Build Environment

Replace the preprocessor definition NDIS51_MINIPORT_DRIVER with NDIS60_MINIPORT_DRIVER.

Driver Initialization
Driver Unload
Miniport Adapter Initialization
Miniport Adapter Halt and Shutdown
Send and Receive Code Paths
  • All NDIS 6.0 miniport drivers are deserialized.

  • Rewrite the send and receive code paths to use NET_BUFFER structures and NET_BUFFER_LIST structures instead of NDIS_PACKET structures.

  • If the driver uses scatter gather DMA (SGDMA) for send operations, add calls to the SGDMA functions as described in the following DMA change summary.

OID Requests
Status Indications
Plug and Play Events
Check for Hang and Reset
New Adapter States
