Hello everyone,
I'm having problem with SR-IOV transparent VLAN.
My host is Fedora 22 and my guest is: pfSense 2.3. The NIC is Intel 82576.
I'm using pfSense Packet Capture to check the packet and find that inbound packet still have the vlan tag. The outbound packet seem fine because the router can receive DHCP discover packet from the guest and then send DHCP offer and ARP request packet to the guest (which still have the vlan tag so the guest does not response).
Loading Ubuntu LiveCD in the same VM does not have this issue so I do not know what is the cause? Any idea to diagnose?
Another problem I have is libvirt does not correctly restore the vf mac address to all zero and then some occasion, there will be duplicate mac address in different vfs which will trigger spoof checking.
I found the related mail here https://www.redhat.com/archives/libvir-list/2015-December/msg00478.html which point to this bug https://bugzilla.redhat.com/show_bug.cgi?id=1302166 . The bug only mention to mellanox cards. Do anyone have the same problem (with igb/igbvf driver) ? Or is it fixed in upstream?
