 The underlying primitive serialize/unserialize functions use network
 byte-order, so there are no structural issues serializing on a
 little-endian host and unserializing on a big-endian host.

-Event-logger, graphical event log viewer
-----------------------------------------
-
-The vppinfra event logger provides very lightweight (sub-100ns)
-precisely time-stamped event-logging services. See
-./src/vppinfra/{elog.c, elog.h}
-
-Serialization support makes it easy to save and ultimately to combine a
-set of event logs. In a distributed system running NTP over a local LAN,
-we find that event logs collected from multiple system elements can be
-combined with a temporal uncertainty no worse than 50us.
-
-A typical event definition and logging call looks like this:
-
-```c
-    ELOG_TYPE_DECLARE (e) = 
-    {
-      .format = "tx-msg: stream %d local seq %d attempt %d",
-      .format_args = "i4i4i4",
-    };
-    struct { u32 stream_id, local_sequence, retry_count; } * ed;
-    ed = ELOG_DATA (m->elog_main, e);
-    ed->stream_id = stream_id;
-    ed->local_sequence = local_sequence;
-    ed->retry_count = retry_count;
-```
-
-The ELOG\_DATA macro returns a pointer to 20 bytes worth of arbitrary
-event data, to be formatted (offline, not at runtime) as described by
-format\_args. Aside from obvious integer formats, the CLIB event logger
-provides a couple of interesting additions. The "t4" format
-pretty-prints enumerated values:
-
-```c
-    ELOG_TYPE_DECLARE (e) = 
-    {
-      .format = "get_or_create: %s",
-      .format_args = "t4",
-      .n_enum_strings = 2,
-      .enum_strings = { "old", "new", },
-    };
-```
-
-The "t" format specifier indicates that the corresponding datum is an
-index in the event's set of enumerated strings, as shown in the previous
-event type definition.
-
-The “T” format specifier indicates that the corresponding datum is an
-index in the event log’s string heap. This allows the programmer to emit
-arbitrary formatted strings. One often combines this facility with a
-hash table to keep the event-log string heap from growing arbitrarily
-large.
-
-Noting the 20-octet limit per-log-entry data field, the event log
-formatter supports arbitrary combinations of these data types. As in:
-the ".format" field may contain one or more instances of the following:
-
--   i1 - 8-bit unsigned integer
--   i2 - 16-bit unsigned integer
--   i4 - 32-bit unsigned integer
--   i8 - 64-bit unsigned integer
--   f4 - float
--   f8 - double
--   s - NULL-terminated string - be careful
--   sN - N-byte character array
--   t1,2,4 - per-event enumeration ID
--   T4 - Event-log string table offset
-
-The vpp engine event log is thread-safe, and is shared by all threads.
-Take care not to serialize the computation. Although the event-logger is
-about as fast as practicable, it's not appropriate for per-packet use in
-hard-core data plane code. It's most appropriate for capturing rare
-events - link up-down events, specific control-plane events and so
-forth.
-
-The vpp engine has several debug CLI commands for manipulating its event
-log:
-
-```
-    vpp# event-logger clear
-    vpp# event-logger save <filename> # for security, writes into /tmp/<filename>.
-                                      # <filename> must not contain '.' or '/' characters
-    vpp# show event-logger [all] [<nnn>] # display the event log
-                                       # by default, the last 250 entries
-```
-
-The event log defaults to 128K entries. The command-line argument "...
-vlib { elog-events nnn } ..." configures the size of the event log.
-
-As described above, the vpp engine event log is thread-safe and shared.
-To avoid confusing non-appearance of events logged by worker threads,
-make sure to code vlib\_global\_main.elog\_main - instead of
-vm->elog\_main. The latter form is correct in the main thread, but
-will almost certainly produce bad results in worker threads.

-G2 graphical event viewer
--------------------------
-
-The g2 graphical event viewer can display serialized vppinfra event logs
-directly, or via the c2cpel tool.
