Furthermore, if the filter only holds onto OID requests so it can pass
down a clone (the most common case) the filter does not need to implement
this routine; NDIS will then automatically request that the lower-level
filter/miniport cancel your cloned OID.
Most filters do not need to implement this routine.

Notification that an OID request has been completed

pended, the FilterOidRequestComplete routine is invoked when the request
is complete. Most requests we've sent are simply clones of requests
received from a higher layer; all we need to do is complete the original
higher request.
However, if this filter driver sends original requests down, it must not
attempt to complete a pending request to the higher layer.
