-   Comparing to general packet classification problem,
-   RSVP needs only several relatively simple rules:
-
-   * (dst, protocol) are always specified,
-     so that we are able to hash them.
-   * src may be exact, or may be wildcard, so that
-     we can keep a hash table plus one wildcard entry.
-   * source port (or flow label) is important only if src is given.
-
-   IMPLEMENTATION.
-
-   We use a two level hash table: The top level is keyed by
-   destination address and protocol ID, every bucket contains a list
-   of "rsvp sessions", identified by destination address, protocol and
-   DPI(="Destination Port ID"): triple (key, mask, offset).
-
-   Every bucket has a smaller hash table keyed by source address
-   (cf. RSVP flowspec) and one wildcard entry for wildcard reservations.
-   Every bucket is again a list of "RSVP flows", selected by
-   source address and SPI(="Source Port ID" here rather than
-   "security parameter index"): triple (key, mask, offset).
-
-
-   NOTE 1. All the packets with IPv6 extension headers (but AH and ESP)
-   and all fragmented packets go to the best-effort traffic class.
-
-
-   NOTE 2. Two "port id"'s seems to be redundant, rfc2207 requires
-   only one "Generalized Port Identifier". So that for classic
-   ah, esp (and udp,tcp) both *pi should coincide or one of them
-   should be wildcard.
-
-   At first sight, this redundancy is just a waste of CPU
-   resources. But DPI and SPI add the possibility to assign different
-   priorities to GPIs. Look also at note 4 about tunnels below.
-
-
-   NOTE 3. One complication is the case of tunneled packets.
-   We implement it as following: if the first lookup
-   matches a special session with "tunnelhdr" value not zero,
-   flowid doesn't contain the true flow ID, but the tunnel ID (1...255).
-   In this case, we pull tunnelhdr bytes and restart lookup
-   with tunnel ID added to the list of keys. Simple and stupid 8)8)
-   It's enough for PIMREG and IPIP.
-
-
-   NOTE 4. Two GPIs make it possible to parse even GRE packets.
-   F.e. DPI can select ETH_P_IP (and necessary flags to make
-   tunnelhdr correct) in GRE protocol field and SPI matches
-   GRE key. Is it not nice? 8)8)
-
-
-   Well, as result, despite its simplicity, we get a pretty
-   powerful classification engine.  */
