[ovs-discuss] DPDK & LLDP & OpenFlow

Hi all,

I use the latest OVS (master branch) running only DPDK ports.  I have 
connected an OpenFlow controller that iteratively sends LLDP packets via 
OpenFlow Packet Out messages across all ports.

I see that LLDP messages finally ends up in lib/netdev-dpdk.c and 
successfully goes throught rte_eth_tx_burst(). But I don't see anything 
coming on other side of the link. It looks the packets get stuck 
somewhere inside dpdk, nic, etc.

Has anyone seen such behavior before? What can I do to figure out the 
problem?

Thanks!
