vf unicast promisc not work in xl710-QDA2 NIC

I try to set PF promisc and vf-true-promisc-support on,but it doesn't work.

 

In my system, PF1 VF1 and PF2 VF2 are assigned to a VM, and when send packets with dstmac are not VF, The VF dropped the packets.

The topology is PF1 connect to ixia1,PF2 connect to ixia2.

When ixia1 send arp broadcast packet to ixia2, the packets can arrive to ixia2 by disable VF spoofcheck.But ixia2 reply a L2 unicast packet and dstmac is not the mac of PF2 VF1, so it was dropped.

VM

VF1 VF1

PF1 PF2

ixia1 ixia2

I heard unicast promist mode can resolv this problem, so I config PF promisc and VF promisc, but it doesn't work.

# ifconfig enp6s0f0 promisc

 

# ifconfig enp6s0f0
