Hello,

Ethernet frames sent to multicast destination address 01:ff:ff:ff:ff:01
not visible on ixgbe & i40e VF PMDs.

PF PMDs receive multicast frames normally.

Tested with DPDK v17.05.0 and
3566af6be7f968c678a867399ddc644fb762873b (current master) 

Regards,
Gregory

By default Intel VF's block multicast. 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
