I see a lot of "complexity of bridging layer" pushback on these changes, and I understand where that is coming from. But really this isn't even, at a high level, really a bridging change. What it's doing is making lwtunnel objects more useful. Now that we have lightweight tunnels and netdevs, w

[PATCH net-next v2 0/5] bridge: per vlan dst_metadata support

2017-01-31 Thread Roopa Prabhu
From: Roopa Prabhu High level summary: lwt and dst_metadata have enabled vxlan l3 deployments to use a single vxlan netdev for multiple vnis eliminating the scalability problem with using a single vxlan netdev per vni. This series tries to do the same for vxlan netdevs in pure l2 bridged networks
