This patch series adds support for sending periodic router advertisements from OVN. The patch is divided into two commits
* Commit 1 introduces a method to ensure that multicast packets are sent only to targets on the local hypervisor * Commit 2 adds the ability to actually send the periodic RAs. This patch series builds on the work in Numan Siddique's "ovn IPv6: Add Router Solicitation responder support and generate Neighbor Solicitation request for unknown" (patch series 11416 if using git-pw). Thus this patch series cannot be merged until that patch series is merged first. There are a couple of points I'd like to bring up with regards to this patch that I would like addressed in reviews: * I placed the logic for sending periodic RAs in pinctrl.c. My reasoning for this was that the closest thing that exists in OVN today is the periodic sending of gratuitous ARP requests, and that is in pinctrl.c. If periodic sending of RAs should be placed into a separate file, please let me know. * In this patch, you will notice that a copy of the put_load() function from ovn/controller/physical.c has been placed in pinctrl.c. My choice was either to make the function public or duplicate it. Given that the function is so small, I see no reason why it would be modified, I went with the duplication choice. However, if it should be done the other way, let me know and I'll go that direction instead. v1 -> v2: * The patchset has been applied on top of patch series 11416. The cover letter above has been adjusted for that change. * Patch 1 has been updated by adding new information to the ovn-architecture manpage that mentions the MLF_KEEP_LOCAL flows installed in table 32.
