Hi All

I have an Intel 82599 with VFs created using Kernel Driver.
Two of the VFs are bound to DPDK Driver.

I'm trying to enable multicast for both VFs with testpmd app but it doesn't
work.
Output below:
testpmd> show port info 0

********************* Infos for port 0  *********************
MAC address: 02:09:C0:5C:65:18
Connect to socket: 0
memory allocation on the socket: 0

Maximum number of MAC addresses of hash filtering: 4096

  qinq(extend) off

I also tried to bind VFs to VFIO driver but this also doesn't work.

So my question is: is it possible to set multicast for VF. If yes then why
testpmd is unable to set it

Setup:
HP Dl380p, Ubuntu 14, Intel 82599

Thanks
Tomasz
