4578 * have an explicit way to indicate packet type; instead:
4579 *
4580 * - If OVS_KEY_ATTR_ETHERNET is present, the packet is an
4581 * Ethernet packet and OVS_KEY_ATTR_ETHERTYPE is the
4582 * Ethertype encoded in the Ethernet header.

4584 * - If OVS_KEY_ATTR_ETHERNET is absent, then the packet's
4585 * root type is that encoded in OVS_KEY_ATTR_ETHERTYPE
4586 * (i.e. if OVS_KEY_ATTR_ETHERTYPE is 0x0800 then the
4587 * packet is an IPv4 packet).
4588 *
4589 * Thus, if OVS_KEY_ATTR_ETHERNET is present, even if it is
4590 * all-wildcarded, it is important to print it.
4591 *
4592 * On the other hand, the userspace datapath supports
4593 * OVS_KEY_ATTR_PACKET_TYPE and uses it to indicate the packet
4594 * type. Thus, if OVS_KEY_ATTR_PACKET_TYPE is present, we need
4595 * not print an all-wildcarded OVS_KEY_ATTR_ETHERNET. */
