As Jakub mentioned, this patch series requires necessary changes to
ovn/northd/ovn-northd.8.xml with the appropriate documentation.

Tested it in a setup as described in:

  http://blog.spinhirne.com/2016/09/the-ovn-load-balancer.html

but with overlay and external networks using IPv6.

I've tried creating an LB both with and w/o a port numbers. All worked
fine. For example:

ovn-nbctl create load_balancer 'vips:"fd66::254"="fc11::130,fc11::131"'
ovn-nbctl create load_balancer 
'vips:"[fc11::62]:80"="[fc11::130]:8000,[fc11::131]:8000"'

Feel free to add my:

Tested-by: Jakub Sitnicki 

However, ovn-nb man-page section for Load_Balancer table needs an update
because right now it says that IPv4 addresses are expected in vips
mapping.

Thanks,
Jakub
