Changes in 1.3.2 (May 2006)---------------------------* Fixed bug* Added -t option to kill pathload_rcv after user specified timeChanges in 1.3.1 (May 2005)---------------------------* Modified to work in 64bit environment  - Thanks to Omid Khalili and Shava Smallen for testing and reporting several  bugs in 64bit environment* Modified to work without thread library* Bug fixes  - for-loop in adjust_offset_to_zero( ) should go upto len-1  Changes in 1.3.0 (Sep 2004)---------------------------* Initial probing rate, when ADR estimate is 0, is changed from min_rate to   avg of min_rate and max_rate. * Bug fixes  - Moved send_latency call after pathload_snd determines max_pkt_sz.  This bug resulted in packet size of 0 being used in send_latency function.  - min_timer_intr set to zero in the pathload_snd_fns.c::send_fleet() code.    This caused floating point exceptions (when it was zero).  - Changed max_pkt_sz to cur_pkt_sz in recv_fleet function. This caused   segmentation fault in certain cases (when trying to free memory).  - Modified pathload sender code such that sender exits (or enters wait state  for new receiver) if it receives either cur_pkt_sz, time_interval or probe_rate  equal to 0.  Changes in 1.2.0 (Apr 2004)---------------------------* Interrupt coalescence changes  Detects IC and uses alternate algorithm (Published in PAM '04).Changes in 1.1.1 (Jan 2004)---------------------------* Bug fixes.  - Make new thread detached in pathload receiver. This fixes a bug in older    version, where receiver would hang after approx 20 fleet as not enough    memory was available to create a new thread and receiver would exit with a    message "Receiver not responding".  - Fixed a bug in sender that would cause sender running in iterative mode to    exit with "Broken pipe" if receiver was killed.  - Simplified code to detect interrupt coalescence.  - Several other minor changes in the codeChanges in 1.1.0 (Apr 2003)---------------------------* Added option to have output in netlogger format.* Implemented function to measure minimum sleep time using select.* Added select so that sender doesnot block and now waits a maximum of 50 sec  for a control message from receiver during a ongoing measurement.  * Reduced the aggregate threshold from .7 -> to .6.* Receiver uses different thread for control messages while getting probing  packets in main thread. Don't use select anymore.
