I am writing a controller to control ovs through openflow protocol.
I found that  when I dump flows from ovs using ovs-ofctl. It shows me so
many fields prefixed with "NXM".
And we plan to use "nxm packet_in_2" format. It also needs nicira
extensions.
So if the controller wants to communicate with ovs using openflow 1.3, I
have to deal with nicira extensions.
But I could not found any document about its format and the corresponding
openflow message format.
Could any one help me ?
thanks.
