Hi Souvik, To my opinion, rte_eth_dev_set_mc_addr_list has nothing to do with rte_eth_allmulticast_enable. rte_eth_allmulticast_enable is enough for the multicast packets. I'm curious about the 1, what MAC addresses are set by rte_eth_dev_set_mc_addr_list? 2, What multicast packets are sent? Thanks.

I am currently using 2.1 DPDK and found that there was a patch in 16.04 for "ixgbe: support multicast promiscuous mode on VF". So I have backported the patch to the 2.1 DPDK but still multicast packets were not coming up to the DPDK app. Then I tried to enable the rte_eth_dev_set_mc_addr_list and with the the packets were coming up properly. Now I have some doubts : 1. Do we have to use both rte_eth_dev_set_mc_addr_list and rte_eth_allmulticast_enable to get the multicast packets. 2. How do we get the mc_addr_list dynamically as I don't see we are using the kni_net_set_rx_mode in rte_kni. Without this the DPDK app will not have any idea to update the mc_addr_list in the PF. 3. Is there any other patches which I should be using to get this functionality working. I am using : DPDK -2.1 Host kernel - 4.4 ( ubuntu) Guest kernel - 3.2 (Debian) Drivers - ixgbe ( for both pf and vf). Thanks in advance for the help and support. -- Regards, Souvik
