Hi I have a setup with Intel 82576NS. Port 0 is connected to internal network and is managed by igb driver Port 1 is connected directly to PC which will serve as traffic generator.
When Port 1 is managed by igb driver eth interface is configured and I am able to connect to traffic generator PC. However when I bind Port 1 to igb_uio driver and start testpmd application, it reports that Link is Down for this port. Tried to seach Mailing list for answer but didn't find any. Any ideas why this happens. (My suspicion is that Traffic Generator PC doesn't have DPDK NIC) Thanks in advance Tomasz Kasowicz Host PC: Intel(R) Xeon(R) CPU E31220 @ 3.10GHz Intel 82576NS Ubuntu 12.04 Kernel Options: iommu=pt intel_iommu=on pci=assign-busses Traffic Generator Inter(R) Core(TM)2 Duo CPU E8400 Intel 82567LF-3 Ubuntu 12.04
