I have a few questions that aren't answered by the packet driver spec.  Can
anyone help me?

I have version 1.05--is there a later version?


access_type():
What is the range of if_number?
When should access_type return BAD_HANDLE?  When out of handles?
When should access_type return TYPE_INUSE?  When the packet type is in use?
Why is typelen a parameter?
Isn't it a fixed quantity for each interface class?
What if I don't have enough space to store their type? Return NO_SPACE?

terminate():
Sounds like the driver shouldn't terminate until and unless all handles have
either been released.  What if a call to terminate() has been made, and
there are other handles in use?  Should the driver terminate after the
last handle has been released?  Sounds like terminate() requires a handle
that *hasn't* been released.  If it returns CANT_TERMINATE, should it also
release the handle?
