NIC drivers can call this function or NdisMSetAttributesEx. Intermediate drivers must call NdisMSetAttributesEx.

  • NdisMSetAttributesEx
    Informs the NDIS library about significant features of the caller's NIC, such as whether it is a bus master and the type of I/O bus on which the NIC can be found, so the miniport driver can call other NdisXxx initialization and configuration routines, particularly the NdisRegisterXxx.

To ensure their portability across Microsoft operating systems that support Win32, most NDIS miniport drivers call only functions exported by the NDIS library and use only macros explicitly declared in the master header file, ndis.h, or in the appropriate efilter.h, ffilter.h, tfilter.h, or afilter.h, if the NDIS uses the system-supplied Ethernet, FDDI, Token Ring, or ARCNET filter-library support to manage bindings for the miniport driver.

However, in addition to the NDIS library functions listed here, a miniport driver might use some of the macros and support routines exported by other kernel-mode components, such as the following:

CONTAINING_RECORD

InitializeListHead

InsertHeadList

InsertTailList

IsListEmpty

RemoveEntryList

RemoveHeadList

For more information about the preceding macro and functions, see Run-time Library Routines.
