Syntax
VOID
FilterDetach(
IN NDIS_HANDLE FilterModuleContext
);

A handle to the context area for the filter module that NDIS will remove from the driver stack. The filter driver created and initialized this context area in the FilterAttach function.
Return Value

Remarks
FilterDetach is a required function. NDIS calls FilterDetach to remove a filter module from a driver stack. NDIS calls FilterDetach when the filter module is in the Paused state.
FilterDetach frees the driver's context areas and other resources (such as buffer pools) for the affected filter module.
After the filter driver returns from FilterDetach, the filter module is in the Detached state.
NDIS calls FilterDetach at IRQL = PASSIVE_LEVEL.
