    I've updated the spec, to include the above and the
other
    corrections.

    ...
    IPFilter hook naming
    --------------------
    For applications that wish to insert hooks before or
after IPFilter
    in the packet stack, the names used by IPFilter are
provided as an
    uncommitted interface:

   
+------------------+--------------------------+-------------
---+
    | Packet Hook      | IPFilter Hook Name       |
Classification |
   
+------------------+--------------------------+-------------
---+
    | NH_PHYSICAL_IN   | "ipfilter_hook_in"      
|   Uncommitted  |
    | NH_PHYSICAL_OUT  | "ipfilter_hook_out"     
|   Uncommitted  |
    | NH_LOOPBACK_IN   | "ipfilter_hook_loop_in" 
|   Uncommitted  |
    | NH_LOOPBACK_OUT  | "ipfilter_hook_loop_out"
|   Uncommitted  |
   
+------------------+--------------------------+-------------
---+

Does this case specify whether IPFilter supplies ordering
hints when
establishing its hooks?  If so, what are they?  (This would
seem to be
useful information for the applications alluded to above to
know.)

As IPfilter does not make use of the ordering hints, there
was
nothing to mention...well, I suppose I should have mentioned
that
it doesn't use them.
