 *
 * dli_grifindex is the group interface index number (for IPMP interfaces).
 *
 * dli_zsrc is the zone identifier for the source of the packet.
 *
 * dli_zdst is the zone identifier for the destination of the packet.
 *
 * A zone number of 0 is the global zone; a zone number of 0xffffffff
 * means that the packet arrived from another host on the network, not
