Hi,
I'm having trouble getting a link up on a ixgbe card. The hardware is a SuperMicro SYS-5018D-FN8T ( https://www.supermicro.nl/products/system/1U/5018/SYS-5018D-FN8T.cfm ) It includes a Intel® Xeon® processor D-1518 with embedded 10G Intel NICs and cs4227 phys to SFP+ ports. The optics in it is an official Intel optics FTLX8571D3BCVIT1 but I tried with some direct attach cables and some active optical tables and other optics as well with the same results. I tried both latest stable 4.4.x and 4.8.0-rc4 kernels There is no errors, just the device stays at NO-CARRIER. Even loading the module with debug=16 doesn't show anything more. Any idea what I can try ?
