  Log Message:
  ovn-northd: Restrict use of unspecified source addresses

Restrict use of the unspecified source addresses (:: and to
traffic necessary to obtain an IP address. DHCP discovery messages for
the IPv4 case, and ICMP6 types necessary for duplicate address detection
for IPv6.

This breaks the existing ovn -- portsecurity : 3 HVs, 1 LS, 3 lports/HV
test since it tests sourcing IPv6 packets from the unspecified address
with and invalid ICMPv6 type (0). Modified this test should be extended
to verify ICMPv6 types for DAD are permitted, and other IPv6 traffic
sourced from the unspecified address are dropped.
