NETPERF CHANGES

2.4.4 (2008-03-30)
-  The LOC_CPU and REM_CPU tests will report their respective beliefs
   as to the number of CPUs present when the verbosity is set to more
   than one.  This can be used when trying to diagnose issues with CPU
   utilization.
-  A kind soul who wishes to remain anonymous provided a patch to
   enable use of sendfile() on OSX.
-  Fix a misplaced \n in a format string of send_tcp_maerts, courtesy
   of Alexander Duyck.
-  There is an experimental global -r option which will allow one to
   include CPU utilization measurements, but make the decision about
   hitting confidence based on the result only.  The test banner will
   reflects this when -r is used.
-  It is no longer necessary to specify a file with the global -F
   option when running a _SENDFILE test.  Netperf will create a
   temporary file and populate it with random data and use that.  If
   running aggregate tests it is strongly suggested one use a -F
   option. Otherwise, the overhead spent creating and populating the
   temporary file will be included in the CPU utilization calculation.
-  The configure script recognizes Solaris 11 and selects the correct
   CPU utilization mechanism - or rather it selects the same mechanism
   as is used in Solaris 10.  Fix courtesy of Andrew Gallatin.
-  Convert a number of struct sockaddr_in's to struct
   sockaddr_storage's and add requisite casts to deal with some abort
   problems on Windows and perhaps other platforms as well. Kudos to
   Alexander Duyck.
-  One can now pass a value of 'x' to the global -f option to specify
   the units as transactions per second.  This is the default for any
   request/response test, which is determined by there being a "double
   `r'" in the name - eg "RR," "rr," "Rr," or "rR."  At present only
   the TCP_RR test actually looks for this to be set.
-  One can request bits/bytes per second as the primary output of a
   TCP_RR test by setting the global -f option to [kmgKMG] as with any
   of the "STREAM" tests.  This converts the primary throughput metric
   to a bitrate (byterate) following the verbosity rules for a STREAM
   test.  Service demand remains usec/Transaction regardless of the
   setting of the global -f option.
   A verbosity level of 2 or more will cause the TCP_RR test to report
   calculated average RTT latency, transaction rate, and inbound and
   outbound transfer rates regardless of the primary units selected
   with the global -f paramter.  If the primary output is transactions
   per second, the reported inbound and outbound transfer rates will
   be 10^6 bits per second, otherwise, they honor the setting of the
   global -f option.
   All of this is EXPERIMENTAL and subject to change without prior
   notice in future versions of netperf.
-  Replace "break" with "break 2" in acinclude.m4 for a socklen macro
-  The default for the requested socket buffer size is changed from 0
   to -1 to enable passing a value of 0 under Windows, which tells that
   stack one wishes to enable copy-avoidance.
-  Call fflush() on each interim result displayed in demo mode to make
   things happier for folks redirecting same to a file.  From Dan
   Yost.
-  In theory each distinct netserver child will have a debug log with
   its pid appended to the name, somewhat like what appears to happen
   under Windows.
-  A new global, command-line option to netperf and netserver has been
   added. The -V option will cause netperf/netserver to display its
   version and exit.
