Thank you for the response.
I am using userspace OVS without DPDK. I do plan to use DPDK at a future
point, but currently am trying to understand the behavior of a pure
userspace ovs switch.
I have put in custom DBG messages in /lib/dpif_netdev. (specifically
dp_netdev_process_rxq_port) but this dbg message doesn't get triggered when
I ping between two hosts connected by a OVS capable switch.
I do see that in this case, the netdev_linux.c module is called, but I
don't know who is calling this module (i.e the entry point to the ovs code
Any input is appreciated.
