# Test {sctp,ip}:::{send,receive} of IPv4 SCTP to a remote host.
#
# This may fail due to:
#
# 1. A change to the ip stack breaking expected probe behavior,
# which is the reason we are testing.
# 2. No physical network interface is plumbed and up.
# 3. No other hosts on this subnet are reachable and listening on ssh.
# 4. An unlikely race causes the unlocked global send/receive
# variables to be corrupted.
#
# This test performs an SCTP association 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 connection setup, 2 during connection teardown)
# 3 x ip:::receive (2 during setup, 1 during teardown)
# 3 x sctp:::receive (2 during setup, 1 during teardown)
