37 * This file implements a translation layer between the BSD networking
38 * infrasturcture and Windows(R) NDIS network driver modules. A Windows
39 * NDIS driver calls into several functions in the NDIS.SYS Windows
40 * kernel module and exports a table of functions designed to be called
41 * by the NDIS subsystem. Using the PE loader, we can patch our own
42 * versions of the NDIS routines into a given Windows driver module and
43 * convince the driver that it is in fact running on Windows.
44 *
45 * We provide a table of all our implemented NDIS routines which is patched
46 * into the driver object code. All our exported routines must use the
47 * _stdcall calling convention, since that's what the Windows object code
48 * expects.

3021 * depends on the API semantics of ExQueueWorkItem(). In our world,
3022 * ExQueueWorkItem() is implemented on top of IoAllocateQueueItem()
3023 * anyway.
3024 *
3025 * There are actually three distinct APIs here. NdisScheduleWorkItem()
3026 * takes a pointer to an NDIS_WORK_ITEM. ExQueueWorkItem() takes a pointer
3027 * to a WORK_QUEUE_ITEM. And finally, IoQueueWorkItem() takes a pointer
3028 * to an opaque work item thingie which you get from IoAllocateWorkItem().
3029 * An NDIS_WORK_ITEM is not the same as a WORK_QUEUE_ITEM. However,
3030 * the NDIS_WORK_ITEM has some opaque storage at the end of it, and we
3031 * (ab)use this storage as a WORK_QUEUE_ITEM, which is what we submit
