Users must send packet\nwith ether MAC destination address the same as pf port MAC address,\nin order to forward packet successfully, but this is an example\nfor forwarding ipv4 multicastpacket. So calling function\nrte_eth_promiscuous_enable() or rte_eth_allmulticast_enable() can\nenable promiscuous mode of all multicast packet. And aslo, DPDK has\nrte API function of rte_eth_dev_set_mc_addr_list() for setting\nspecific multicast filter table for specific multicast IP address,\nbut this example do not support this configuration, so it need to\nbe enable multicast promiscuous mode instead.\n\nSigned-off-by: Wei Zhao <wei.zhao1@intel.com>\n---\n examples/ipv4_multicast/main.c | 2 +-\n 1 file changed, 1 insertion(+), 1 deletion(-)",
