- # Test sctp:::state-change and sctp:::{send,receive} by connecting to
- # the local discard 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. An unlikely race causes the unlocked global send/receive
- # variables to be corrupted.
- #
- # This test performs a SCTP connection and checks that at least the
- # following packet counts were traced:
- #
- # 7 x ip:::send (4 during the setup, 3 during the teardown)
- # 7 x sctp:::send (4 during the setup, 3 during the teardown)
- # 7 x ip:::receive (4 during the setup, 3 during the teardown)
- # 7 x sctp:::receive (4 during the setup, 3 during the teardown)
- #
- # The actual count tested is 7 each way, since we are tracing both
- # source and destination events.
- #
