I do see there is a limitation mentioned in the release notes of DPDK that 16.27. I40e VF may not receive packets in the promiscuous mode Description: Promiscuous mode is not supported by the DPDK i40e VF driver when using the= i40e Linux kernel driver as host driver. Implication: The i40e VF does not receive packets when the destination MAC address is un= known. Resolution/Workaround: Use a explicit destination MAC address that matches the VF. Affected Environment/Platform: All. Driver/Module: Poll Mode Driver (PMD). Do this mean that multicast promiscuous mode is also not supported ? I am c= urrently facing issues with receiving packets multicast packets for IPv6 wh= ich is making IPv6 to fail with i40evf pmd. I am currently using 17.11.2 DPDK with the Centos 7.5 and i40e 2.4.6 versio= n on the host. I have the rte_eth_allmulticast_enable() also set for the po= rt but still I see all multicast packets are not reaching the pmd. Also if promiscuous mode has to be turned off then how should we add multic= ast address to the PF from the VF ? -- Regards, Souvik
