    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.)
