Please hold on this patch. Our QE reported that with bare NIC, the backup NIC can't receive the NS messages even after joining the multicast MAC group. But after remove the backup NIC from bond, the NIC interface could receive the NS message.
This is weird, it looks the backup NIC dropped the NS message somewhere, even using tcpdump (the NIC will be in promisc mode) I can't capture the NS message on backup slave.
I need to debug more.
After debug, I find it's a driver issue. The issue exists with ice dirver NIC. I tried with a mlx5 NIC and the patch works good for me.
So I think you can start review this patch when you have time. I will debug the ice driver later.
Thanks Hangbin
