I tested tcp traffic in various setups (with mlx5 nic as physical port): - external host <-> ovs <-> kernel host - external host <-> ovs <-> kernel vm - kernel vm <-> ovs <-> kernel host - kernel vm1 <-> ovs <-> kernel vm2 The changes may need more eyes on the netdev-linux parts, but the rest looks good to me.
