+ * Local port number conventions:
+ *
+ * When a user does a bind(2) or connect(2) with a port number of zero,
+ * a non-conflicting local port address is chosen.
+ * The default range is IPPORT_HIFIRSTAUTO through
+ * IPPORT_HILASTAUTO, although that is settable by sysctl.
+ *
+ * A user may set the IPPROTO_IP option IP_PORTRANGE to change this
+ * default assignment range.
+ *
+ * The value IP_PORTRANGE_DEFAULT causes the default behavior.
+ *
+ * The value IP_PORTRANGE_HIGH changes the range of candidate port numbers
+ * into the "high" range.  These are reserved for client outbound connections
+ * which do not want to be filtered by any firewalls.  Note that by default
+ * this is the same as IP_PORTRANGE_DEFAULT.
+ *
+ * The value IP_PORTRANGE_LOW changes the range to the "low" are
+ * that is (by convention) restricted to privileged processes.  This
+ * convention is based on "vouchsafe" principles only.  It is only secure
+ * if you trust the remote host to restrict these ports.
+ *
+ * The default range of ports and the high range can be changed by
+ * sysctl(3).  (net.inet.ip.port{hi,low}{first,last}_auto)
+ *
+ * Changing those values has bad security implications if you are
+ * using a a stateless firewall that is allowing packets outside of that
+ * range in order to allow transparent outgoing connections.
+ *
+ * Such a firewall configuration will generally depend on the use of these
+ * default values.  If you change them, you may find your Security
+ * Administrator looking for you with a heavy object.
+ *
+ * For a slightly more orthodox text view on this:
+ *
+ *            ftp://ftp.isi.edu/in-notes/iana/assignments/port-numbers
+ *
+ *    port numbers are divided into three ranges:
+ *
+ *                0 -  1023 Well Known Ports
+ *             1024 - 49151 Registered Ports

+ * Overall structure of dummynet (with WF2Q+):
+
+In dummynet, packets are selected with the firewall rules, and passed
+to two different objects: PIPE or QUEUE.
+
+A QUEUE is just a queue with configurable size and queue management
+policy. It is also associated with a mask (to discriminate among
+different flows), a weight (used to give different shares of the
+bandwidth to different flows) and a "pipe", which essentially
+supplies the transmit clock for all queues associated with that
+pipe.
+
+A PIPE emulates a fixed-bandwidth link, whose bandwidth is
+configurable.  The "clock" for a pipe can come from either an
+internal timer, or from the transmit interrupt of an interface.
+A pipe is also associated with one (or more, if masks are used)
+queue, where all packets for that pipe are stored.
+
+The bandwidth available on the pipe is shared by the queues
+associated with that pipe (only one in case the packet is sent
+to a PIPE) according to the WF2Q+ scheduling algorithm and the
+configured weights.
+
+In general, incoming packets are stored in the appropriate queue,
+which is then placed into one of a few heaps managed by a scheduler
+to decide when the packet should be extracted.
+The scheduler (a function called dummynet()) is run at every timer
+tick, and grabs queues from the head of the heaps when they are
+ready for processing.
+
+There are three data structures definining a pipe and associated queues:
+
+ + dn_pipe, which contains the main configuration parameters related
+   to delay and bandwidth;
+ + dn_flow_set, which contains WF2Q+ configuration, flow
+   masks, plr and RED configuration;
+ + dn_flow_queue, which is the per-flow queue (containing the packets)
+
+Multiple dn_flow_set can be linked to the same pipe, and multiple
+dn_flow_queue can be linked to the same dn_flow_set.
+All data structures are linked in a linear list which is used for
+housekeeping purposes.
+
+During configuration, we create and initialize the dn_flow_set
+and dn_pipe structures (a dn_pipe also contains a dn_flow_set).
+
+At runtime: packets are sent to the appropriate dn_flow_set (either
+WFQ ones, or the one embedded in the dn_pipe for fixed-rate flows),
+which in turn dispatches them to the appropriate dn_flow_queue
+(created dynamically according to the masks).
+
+The transmit clock for fixed rate flows (ready_event()) selects the
+dn_flow_queue to be used to transmit the next packet. For WF2Q,
+wfq_ready_event() extract a pipe which in turn selects the right
+flow using a number of heaps defined into the pipe itself.

+ * The TCPT_REXMT timer is used to force retransmissions.
+ * The TCP has the TCPT_REXMT timer set whenever segments
+ * have been sent for which ACKs are expected but not yet
+ * received.  If an ACK is received which advances tp->snd_una,
+ * then the retransmit timer is cleared (if there are no more
+ * outstanding segments) or reset to the base value (if there
+ * are more ACKs expected).  Whenever the retransmit timer goes off,
+ * we retransmit one unacknowledged segment, and do a backoff
+ * on the retransmit timer.
+ *
+ * The TCPT_PERSIST timer is used to keep window size information
+ * flowing even if the window goes shut.  If all previous transmissions
+ * have been acknowledged (so that there are no retransmissions in progress),
+ * and the window is too small to bother sending anything, then we start
+ * the TCPT_PERSIST timer.  When it expires, if the window is nonzero,
+ * we go to transmit state.  Otherwise, at intervals send a single byte
+ * into the peer's window to force him to update our window information.
+ * We do this at most as often as TCPT_PERSMIN time intervals,
+ * but no more frequently than the current estimate of round-trip
+ * packet time.  The TCPT_PERSIST timer is cleared whenever we receive
+ * a window update from the peer.
+ *
+ * The TCPT_KEEP timer is used to keep connections alive.  If an
+ * connection is idle (no segments received) for TCPTV_KEEP_INIT amount of time,
+ * but not yet established, then we drop the connection.  Once the connection
+ * is established, if the connection is idle for TCPTV_KEEP_IDLE time
+ * (and keepalives have been enabled on the socket), we begin to probe
+ * the connection.  We force the peer to send us a segment by sending:
+ *	<SEQ=SND.UNA-1><ACK=RCV.NXT><CTL=ACK>
+ * This segment is (deliberately) outside the window, and should elicit
+ * an ack segment in response from the peer.  If, despite the TCPT_KEEP
+ * initiated segments we cannot elicit a response from a peer in TCPT_MAXIDLE
+ * amount of time probing, then we drop the connection.
