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
