I did some testing of SR-IOV a while ago on an Intel NIC. I remember having to fiddle with it to get it working, so here are a new notes/questions you might find useful (or maybe not :-)). Are there any errors in the stats on the physical function (ethtool -S ) ? Since you are receiving packets the MAC is probably correct. But anyway: Did you check the MAC addresses of the VF using "ip link show " - do they match what DPDK uses ? Is spoof checking enabled on the PF ? My tests were with an XL710 only using Linux (no DPDK). To be able to TX from the VF after changing stuff with "ip link set..." I think I may have had to reset the VF or PF using "ip link set .. down/up". I know I'm not exactly providing any answers here - and my memory isn't helping - but maybe something can point you in the right direction.
