# OVN_CHECK_PACKETS([PCAP], [EXPECTED])
#
# This compares packets read from PCAP, in pcap format, to those read
# from EXPECTED, which is a text file containing packets as hex
# strings, one per line.  If PCAP contains fewer packets than
# EXPECTED, it waits up to 10 seconds for more packets to appear.
#
# The implementation is an m4 macro that is mostly implemented in
# terms of a shell function.  This reduces the size of the generated
# testsuite file since the shell function is only emitted once even
# when this macro is invoked many times.

# 3. When port security is turned on, the switch drops packets from the wrong

# 5. The switch drops all packets with a multicast source address.  (This only
#    affects behavior when port security is turned off, since otherwise port
#    security would drop the packet anyway.)
#
# 6. The switch delivers packets with an unknown destination to logical
#    switch ports with "unknown" among their MAC addresses (and port
#    security disabled).
#
# 7. The switch drops unicast packets that violate an ACL.
#
# 8. The switch drops multicast and broadcast packets that violate an ACL.
#
# 9. ARP requests to known IPs are responded directly.
#
# 10. No response to ARP requests for unknown IPs.
