From mboxrd@z Thu Jan 1 00:00:00 1970 From: Wei Zhao Subject: [PATCH] examples/ipv4_multicast: enable multicast promiscuous for all port Date: Wed, 17 Oct 2018 15:41:26 +0800 Message-ID: <1539762086-15569-1-git-send-email-wei.zhao1@intel.com> Cc: stable@dpdk.org, qi.z.zhang@intel.com, ferruh.yigit@intel.com, Wei Zhao To: dev@dpdk.org Return-path: List-Id: DPDK patches and discussions List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: dev-bounces@dpdk.org Sender: "dev" 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 aslo, 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.
