Re: [ovs-discuss] disable datapath

Hi Amrane, that’s the expected behavior. The 1st packet of a flow goes up to userspace – and there’s a context switch for that. After classification 1 cache entry will be added in the megaflow table and another cache entry into the microflow table, both these 2 caches are into the kernel. So

Referring to OVS in userspace, the function dp_netdev_process_rxq_port() calls netdev_rxq_recv() which, depending on the type of interface, will call the specific function, eg for a dpdk IF it will call dp_netdev_process_rxq_port() for an internal interface it calls netdev_linux_rxq_recv(). Then
