Hi Flavio and all: Is there a way to support software TSO for DPDK tunnel network ? I have tried userspace TSO function, and running on tunnel network, I have got the following error: "Tunneling packets with HW offload flags is not supported: packet dropped" So is there a way to work around if we would support both vlan and tunnel network on the same compute node ? Thanks Timo
