Tom, Since v3.14, when a tunneled (say VXLAN/GRE) packets are received on the physical interface, they go through GRO aggregation before being delivered up to the tunnel "device" (e.g either vxlan/gre netdevice or OVS vxlan/gre vport) -- so in that respect, can you elaborate a little further why we want to GRO them again? Or. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
