Is this IOCTL still supported on NDIS 6.x platforms? In particular, can I
still use this IOCTL on these platforms to plumb proprietary OIDs (i.e., OID
value >= 0xFF000000) to a driver? I've heard the this IOCTL was in the
process of being deprecated, and it seems that we have problems with it and
proprietary OIDs on NDIS 6.x.
