Support Nicira Openflow extensions

[wenyingd]

Hi,

I found that current flow matchfield and actions only support parts of standard Openflow messages. Do you have a plan to support Nicira extensions in flow entries?

I also found that controller only supports listen on TCP connections. Will it support Unix Domain Socket in the future?

Will be happy to look at a PR. Can you please list the extensions that you need support for?
