------------------------------------------------------------


SUPPORTED_DHCP_OPTS_MAPPING is a dictionary that maps neutron dhcp-option names to ovn dhcp-option names. OVN dhcp-option ia_addr corresponds with neutron dhcp-option names 'ia-addr' or '5'. However, there is a type here and the corresponding OVN value is defined as ip_addr instead of ia_addr [1]

Definition of ia_addr from OVN code: [2]

The following openstack command created a wrong entry in the OVN NBDB DHCP_OPTIONS
$ openstack port create --network tempest-DHCPTest-980691237 --extra-dhcp-option name=ia-addr,value=2001::2001,ip-version=6 port-test-202

# ovn-nbctl list dhcp_options c9b0f6c0-c1bf-4e91-9e66-5e75491ae9e5
_uuid : c9b0f6c0-c1bf-4e91-9e66-5e75491ae9e5
cidr : "2001:db8::/64"
external_ids : {"neutron:revision_number"="0", port_id="1188bca5-4b75-4810-a9a0-38ecc96d0274", subnet_id="567272f0-f1b8-423c-a939-9dea6b5e26ab"}
options : {dhcpv6_stateless="true", ip_addr="2001::2001", server_id="fa:16:3e:ce:f4:67"}
