[ovs-dev] OF1.1+ Groups

OK, I just sent a patch, and I'll try to post more as time allows.
Unfortunately, I'm working from a non-git repo, based off a stale snapshot
of OVS, with layers of local hacks and cruft dating back to OVS 0.9 (WDP!).
So it's a bit harder than it should be to upstream this stuff.

Ben, I don't mean to cause you grief. :) Having _any_ implementation of
groups upstream would make my life much easier, and I'll happily take
whatever you've got brewing in lieu of mine. My only real concerns are that
the ofproto-provider API abstracts the wire protocol and supports async ops.

Thanks,
Casey
