Hi,
I am developing a monitoring filter driver in NDIS, using the famous ndislwf as the reference.
I am sending a few OIDs through this filter driver, DOT11 specific OIDs go to miniport, but generic OIDs are getting lost. Can anyone, throw some light on it.
Cheers,
Sheetal
Fetch the OID_GEN_SUPPORTED_LIST from the miniport. Verify that the OIDs you are querying are actually supported by the miniport. Understand that some mandatory NDIS 5 OIDs are NOT required to be supported by NDIS 6 miniports.
Having said that, making queries for some OIDs may be supported at a higher level in the stack. For example, if you make the queries on the binding above the Microsoft native Wi-Fi driver they may be answered by the LAN emulator.
Just guessing here…

Thanks Thomas!
I have a notion that my filter driver is sitting below wifi-filter
driver, though I have no way of verifying that. This generic oid is
supported by the miniport driver, I am sure of that.
Thanks,
Sheetal

You said it is a monitoring filter. If so, then it is probably bound both
above and below the Microsoft modifying LWF.
If your LWF is a modifying filter (like the WDK LWF sample…), then it
probably cannot bind below the Microsoft LWF.

It is a monitoring driver, so yes, it should bound both above and below
the LWF driver, but then why doesn’t it pass the generic OIDs to the
miniport driver, can it be bcos, there is some specific structure to
pass generic OIDs, and the structure that I am using is not conforming
to the standards?
