From: Wei Zhao Date: Wed, 17 Oct 2018 07:41:26 +0000 (+0800) Subject: examples/ipv4_multicast: enable multicast promiscuous X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=23021f1c6bb8a5e35cf92dfe91ca9ce171b06997;p=dpdk.git examples/ipv4_multicast: enable multicast promiscuous This example has not been enable for receiving multicast packet, so it will drop multicast packet. Users must send packet with ether MAC destination address the same as pf port MAC address, in order to forward packet successfully, but this is an example for forwarding ipv4 multicastpacket. So calling function rte_eth_promiscuous_enable() or rte_eth_allmulticast_enable() can enable promiscuous mode of all multicast packet. And also, DPDK has rte API function of rte_eth_dev_set_mc_addr_list() for setting specific multicast filter table for specific multicast IP address, but this example do not support this configuration, so it need to be enable multicast promiscuous mode instead.
