When OVS needs to add a vxlan tunnel device, OVS can create the vxlan device and check the parameters for the flag. If the flag does not exist then fallback to vport-create. This only needs to be done for very first tunnel device. Thats how most of features are supported in OVS. Sorry, but I do not see where is the confusion. -- 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
