7c6591b4f6 Update documentation
Device name actually uses LUID index only. Not an entire LUID. IfType
in LUID is always 53 (IF_TYPE_PROP_VIRTUAL).

0dac9b2bc7 Use CSQ instead of StartIO
This also introduces a proper queueing and refcounting system, which
should increase performance and allow for IRP cancelation.

9704a4d11f Terminate device connection on NDIS pause
If device connection is not terminated on NDIS pause, the driver doesn't
unload when adapter is disabled. This also prevents driver updates
without reboot.

2e35974a24 Fix ActiveNBLCount management in TunDispatchWrite()
The ActiveNBLCount must be bumped _before_ adapter state is checked.
Otherwise, there is a window of code that may allow adapter transition
from pausing to paused state, followed by a
NdisMIndicateReceiveNetBufferLists() call.
