I wanted to send you an update. (Yes, I'm still working the problem). At first I thought there was some issue with the VF not getting broadcast packets from the PF because it never saw the ARPs from the PF. However, I set up a pktgen test and I'm able to send both directed and broadcast packets from the PF to the VF and the VF receives them all. It is specifically the ARP packets that the VF is not seeing. Since it never sees ARPs from the PF no communication can be established. I recall (I think) that you manually set an ARP entry for the VF but the VF still didn't receive packets, so there must be something else going on. (Or my memory is incorrect). Anyway, still digging and eliminating possibilities. Once I've eliminated all the possible causes then hopefully I'll be left with a solution. We'll see. It's quite a mystery. - Greg ------------------------------------------------------------------------------ _______________________________________________ E1000-devel mailing list E1000-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/e1000-devel To learn more about Intel® Ethernet, visit http://communities.intel.com/community/wired
