# This is the LSALR_6 IPv6 NETWORK TEST MODULE
# This script is transplanted from staf/tests/net/lsalr.stf to support IPv6.
#
#########################################################################
# NOTES ON OPERATION AND ERROR HANDLING:
# This script is called by staf.eng, which is the main test harness.
# Standard output gets recorded in the test module log file by staf.eng.          
#
# Variable maxwarn is checked by staf.eng in the "chk_err()" monitoring process,               
# by grep'ing the log file of this test module.
# If maxwarn is exceeded, the staf.eng script will kill this test module.
# There are two formats for the error echos to the log files;
#
# 1.   echo "!ERROR: blah blah foo bar";
#      which will terminate the test.  If the test harness detects
#      a string match with "!ERROR", then all testing terminates.
#
# 2.   echo "!WARNING: blah blah foo bar";
#       The above format "!WARNING:" will make the log file entry,
#       but all testing will continue, no termination of tests,
#       UNLESS maxwarnings variable is exceeded.
#
# DANGER!!:  Even if you do not intend to use WARNING messages, variable
# maxwarn *MUST* be defined and the "maxwarnings=" line *MUST* be
# echo'ed to the logfile.  This syntax is mandatory.
