# Send packets between all pairs of source and destination ports:
#
# 1. Unicast packets are delivered to exactly one logical switch port
#    (except that packets destined to their input ports are dropped).
#
# 2. Broadcast and multicast are delivered to all logical switch ports
#    except the input port.
#
# 3. When port security is turned on, the switch drops packets from the wrong
#    MAC address.
#
# 4. The switch drops all packets with a VLAN tag.
#
# 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.
