To allow multicast you have to do > some configuration on the PF. > Hello Stephen, I configured 2 VFs on IXBGE v5.1.3 PF, CentOS-6.7 (2.6.32-573) VF-0 operated by kernel ixgbevf driver. It receives Ethernet multicast frames without any additional changes to PF VF-1 operated by DPDK PMD. It does not receive any multicast frame at all. I tried to set up DPDK multicast support with rte_eth_allmulticast_enable() and rte_eth_dev_set_mc_addr_list() Regards, Gregory
