Please don't drop the mailing list. A number of extensions exist in "include/openflow/nicira-ext.h". If you run "git blame" on that file, you'll see a bunch of commit ids. You can then run "git show" on the commit id, and see how the extension was added. For example, "git show fb8f22c1" will show you a commit for exporting IPFIX statistics.
