# Test sctp:::state-change and sctp:::{send,receive} by connecting to
# the remote http service.
# A number of state transition events along with sctp send and receive
# events for the message should result.
#
# This may fail due to:
#
# 1. A change to the ip stack breaking expected probe behavior,
#    which is the reason we are testing.
# 2. The lo0 interface missing or not up.
# 3. The remote ssh service is not online.
# 4. An unlikely race causes the unlocked global send/receive
#    variables to be corrupted.
#
# This test performs a SCTP association to the http service (port 80) and
# checks that at least the following packet counts were traced:
#
# 4 x ip:::send (2 during setup, 2 during teardown)
# 4 x sctp:::send (2 during setup, 2 during teardown)
# 3 x ip:::receive (2 during setup, 1 during teardown)
# 3 x sctp:::receive (2 during setup, 1 during teardown)
#
