The route-table code is useful outside the scope of Open vSwitch.
In a subsequent patch we will expose the route-table data
structures to allow projects compiling against the private Open
vSwitch library to consume this data.
The rtnetlink rtmsg rtm_table variable can hold route table IDs no
higher than 256.
Use the rtnetlink RTA_TABLE route attribute instead, which can
represent a 32 bit integer worth of route tables.
