v3 -> v4 changes
----------------
* Addressed the v3 review comments
* Renamed the action name from "dhcp_offer" to "put_dhcp_opts".
* The action "put_dhcp_opts" will now store the result in the OVS register to indicate
the success or failure of the action.
v2 -> v3 changes
----------------
* Removed RFC tag
* Added a new table 'Subnet' in NB DB to store the DHCP options. A new column 'subnets'
is added in 'Logical_Switch' table which refers to this table.
* Added new commands in ovn-nbctl to create and delete subnets belonging to a lswitch
and to set DHCP options.
* Added a new table 'DHCP_Options' in SB DB to store the supported DHCP option codes.
* Added test cases.
v1 -> v2 changes
--------------
* Added basic documentation
* Added support for classless static routes - dhcp option 121
* Added a new egress table (Table 0) to skip the ACL stages for response dhcp packets.
This is required until the below reported bug is fixed.
Please see - http://openvswitch.org/pipermail/dev/2016-April/069542.html
* Added support for storing dhcp options for multiple subnets belonging
to a lswitch.
Example.
If a lswitch has logical ports having IPv4 addresses belonging to 2 subnets - 10.0.0.0/24 and 20.0.0.0/24,
Then the DHCP options needs to be stored in Logical_Switch.dhcp_options as :
"10.0.0.0/24": "{"server_id": "10.0.0.1", "lease_time": "43200",
"mtu": "1450", "netmask": "255.255.255.0",
"router": "10.0.0.1", "dns_server": "{7.7.7.7,8.8.8.8}",
"server_mac": "fa:16:3e:3e:b8:8a"}"
"20.0.0.0/24": "{"server_id": "20.0.0.1", "lease_time": "43200",
"mtu": "1450", "netmask": "255.255.255.0",
"router": "20.0.0.1", "server_mac": "fa:16:3e:3e:b8:8b",
"classless_static_route": "{30.0.0.0/24,20.0.0.4, 0.0.0.0/0,20.0.0.1}"}"
* Few other small changes.
TODO :
* Add a new table in southbound db and store the supported dhcp option names and codes.
* Test cases
With v3 hoping to remove the RFC tag.
