The question came up in the Red Hat/VMware call this morning of whether Gandi has built-in support for mailing lists. (I don't have a list of everyone in the meeting so I'm just sending this To: everyone I could think of off-hand.) If so, then it would make sense to use them for OVN mailing lists

[ovs-discuss] #ovscon week of Dec. 7

Hi Jan and Rohith. LinkedIn took down all of the slides from the Open vSwitch 2017 Conference because someone alleged copyright infringement against your slides. Does this make any sense to you? I don't have a copy of the slides (because they were on SlideShare only). Can you pass them along?

Re: [ovs-discuss] Netlink for Dump-flow command

I don't see how this can hope to dump flows because it doesn't have the name of the Generic Netlink group for the flow table in it anywhere. It also has some oddities that might show a misunderstanding of how Netlink works. A netlink dump operation can't fail due to packet drops or buffer overrun
