Introduce IPv6 Prefix delegation state machine according to RFC 3633
https://tools.ietf.org/html/rfc3633.
Add handle_dhcpv6_reply controller action to parse advertise/reply from
IPv6 delegation server.
Introduce logical flows in ovn router pipeline in order to parse dhcpv6
advertise/reply from IPv6 prefix delegation router.
This series relies on the following OVS commit:
https://github.com/openvswitch/ovs/commit/cec89046f72cb044b068ba6a4e30dbcc4292c4c1
Changes since v8:
- move prefixd routine declaration in a common place
- rely on datapath_is_switch utility routine
- s/unisgned/uint32_t
- remove sleep in unit test and rely on ovn utility macros
- always overwrite interface name and timeout values in dibbler configuration
Changes since v7:
- fixed a bug inserting the configured prefix as hint in dhcp pd messages
restarting ovn controller
- removed pfd entry from ipv6_prefixd hash if prefix delegation has been
disabled for this port
- check in system-ovn.at that the configured prefix is inserted as hint in dhcp
pd messages
Changes since v6:
- fix documentation
- convert handle_dhcpv6_reply from netsted to plain action
- code reworking to reduce cpu utilization
- insert configured prefix as hint in dhcp pd messages
Changes since v5:
- introduce ipv6_prefix column in logical_router_port table to save ipv6 prefix
received from delegation router
Changes since v4:
- improve unit test support
- fix ovn-controller crash
- confifure prefixes received from delegation router in RA
- allow the requesting router to rely on lla address for PD protocol
Changes since v3:
- cosmetics
- add a provider bridge in the unit-test deployment and add a localnet
port to the deployment to access the underlay network
- request IPv6 prefix even for bar router logical port in the unit-test
deployment
Changes since v2:
- add unitest support in system-ovn.at
Changes since v1:
- rebase on top of ovn master branch
- request an IPv6 prefix for each 'downstream' logical router port marked with
prefix set to true
- add missing documentation
- rename dhcp6_server_pkt in handle_dhcpv6_reply
